Embodiment
Hereinafter is described various aspect of the present invention.Should be easy to understand, the teaching among this paper can embodied in various forms and any ad hoc structure disclosed herein, function or both be merely representational.Based on the teaching among this paper, it will be understood by one of ordinary skill in the art that can be independent of any others implement aspect disclosed herein and can make up in every way in the said aspect both or both more than.For instance, but but use any number the aspect facilities and equipments or the hands-on approach of being stated among this paper.In addition, use other structure, functional, or append to or be different among this paper the one or more structure in the institute statement aspect and functional this equipment of implementing and maybe can put into practice the method.For instance, in certain aspects, a kind of method of deal with data comprises: receive data, the data that wherein received comprise by another device obtain and preliminary treatment to be used for the analogue data of wireless transmission; And the data that processing is received are to extract by at least one represented characteristic of analogue data.In addition, in certain aspects, a kind of method of deal with data also comprises treated transfer of data to other device.
Fig. 1 explains the exemplified aspect of communication system 100, and wherein first wireless device 102 can be communicated by letter with second wireless device 104 via wireless communication link 106.In some embodiments, device 102 and 104 can comprise at least a portion of wireless network.For instance, device 102 and 104 can be relative to each other join and optionally with one or more other apparatus associated to set up or to add the network of human body local area network network, personal area network or a certain other type.
In certain aspects, device 102 and 104 makes device 104 can represent wireless device 102 to carry out processing through debugging.For instance, be not to carry out given processing operation at device 102 places, but can processing be unloaded to device 104.For this reason, device 102 and 104 comprises that respectively one or more processor modules 108 and 110 come executable operations to handle to promote this unloading.In addition, device 102 and 104 comprises the transceiver 112 and 114 that is used between device 102 and 104, sending data respectively.
Can in various situations, use unloading to handle, the multiple arrangement that wherein has different abilities communicates with one another a certain functional to support.For instance, the wireless human body local area network network can comprise one or more wireless medical transducers that are distributed on the user's body.In the said transducer each can send to the data that sensed the Centroid of mobile phone for example or personal digital assistant (" PDA ").Another instance relates to the wireless headset (for example, earphone) of communicating by letter with mobile phone, music player or a certain other device.Another instance is the tire pressure monitor that is arranged in automotive wheel, and wherein monitor sends it back the device that instrument board is installed with pressure reading via Radio Link.In said situation, device one in (for example, transducer and telephone headset) has substantially than low-complexity and than another device (for example, mobile phone or the device of instrument board is installed) and consumes less power substantially.
Usually, for example described low-complexity and low-power device generation need used the initial data that handle before.The echo that the instance of this processing is included in the telephone headset place is eliminated data compression and the audio compression with the effect that reduces ambient noise, equilibrium, heartbeat waveform.Under some situations, treated data are sent to another device supply final the use.For instance, can, it compress before being transferred to the remote-control device that is used for playback by the voice data that telephone headset produced.Under other situation, treated data are finally used at low-complexity, low-power device place.For instance, initiatively noise reduces the warp modification voice data that is created in the playback of telephone headset place.Routinely, on low-complexity, low-power device, carry out the processing that preceding text are discussed.

In the instance of Fig. 1, device 102 comprises one or more input units 116, and said input unit 116 produces the Wave data that possibly handle.In some embodiments, treat to comprise initial data by the data that device 104 is handled.For instance, from any purpose except that being transferred to device 104, device 102 can not handled the data from input unit 116.Therefore, device 102 not deal with data to improve by the represented any characteristic of data.As a particular instance, device 102 not deal with data for example to improve attribute by frequency response, signal to noise ratio or the accuracy of the represented multimedia waveform of data, biological waveform or surrounding environment waveform.
In certain aspects, device 102 comprises preprocessor 118, but said preprocessor 118 preprocessed datas (for example, original analog data) are to be used to be transferred to device 104.For instance, preprocessor 118 can be carried out waveform processing to data.This waveform processing can comprise (for example) pulse code modulated coding or ∑-Δ modulating-coding.Therefore, opposite with the Wave data of further handling (for example, through compression, like what can in conventional system, transmit), device 102 can be transferred to device 104 with Wave data.
In certain aspects; Improvement by data (for example; The raw analog waveform data) at least one represented characteristic can comprise at least one represented characteristic of data (for example, original analog data) that extraction (for example, by extractor assembly 124) is produced by device 102.For instance, extraction can relate to from the data that received (representing original sense data) extraction voice signal, extracts biological parameter (for example, heartbeat waveform), extract surrounding environment parameter (for example, pressure waveform) or a certain other similar operations.Advantageously, can improve by the mode of the represented characteristic of data and carry out this process.For instance, extraction can relate to filtering, denoising, noise removing or a certain other proper technology.
In certain aspects, extraction can relate to the indication of extraction about the data (representing original sense data) that received.For instance, extraction can comprise the indication of extracting biological parameter (for example, heart rate value), indication or a certain other similar indication of extracting surrounding environment parameter (for example, force value).In addition, can improve by the mode of the represented characteristic of data and carry out this process.For instance, the indication of heart rate (for example, as deriving from a plurality of transducers that detect heartbeat waveform) can be through equalization to provide improved final heart rate value.Can carry out similar operations to be used for other indication of biology or surrounding environment parameter.Improve characteristic and also can comprise machine readable property or the human-readable property of improvement by the represented value of analogue data.The indication of for instance, extracting or calculating heart rate (or a certain other parameter) can improve the machine readable property of analogue data or the characteristic of human-readable property.Here, can through future the autobiography sensor pulses switch be the indication that numerical heart rate value (or value of a certain other type) obtains (for example, extract or calculate) heart rate (or a certain other parameter).
With extracting (or after extracting), waveform processor 136 can be carried out the waveform processing of wanting to the Wave data that is extracted.For instance; To discuss more in detail like hereinafter; This waveform processing can relate to through execution is for example balanced, echo is eliminated, the operation of initiatively noise removing, the calculating of filter tap, sidetone processing, biological relevant (for example, medical treatment is correlated with) processing, voice command and identification and ambient environmental conditions processing improves at least one characteristic of data.
Handle at least one attribute that can improve characteristic by this.This attribute can be about (for example) frequency response, signal to noise ratio or accuracy.In certain aspects, leaching process can comprise (for example) in fact reconstruct represent data by device 102 Wave datas (for example, initial data) that produced.
In certain aspects, the result of leaching process can provide the data of comparing the less degradation with at least one characteristic with the data that produced by device 102 (for example, simulation initial data).For instance, and in the original analog data, compare, with respect to by the represented characteristic of data (for example, audio volume control) extract in the data and can have less noise.Likewise, the value that extracts any interference correlated components in the data can be less than the value of this component in the original analog data.Should be appreciated that performed processing (for example, about by the represented characteristic of data) can be different from the processing (for example, compression or decompressed data) of data being carried out simple operations here.
Characteristic by data are represented can be about the various aspects of various types of data (for example, multi-medium data, biological data and ambient data) and said data.For instance, can comprise audio frequency, music, voice, speech, video, heartbeat, blood pressure, body temperature, oxygen concentration levels, glucose level, pressure, temperature, speed, acceleration or a certain other incident or condition by the represented characteristic of data.
In addition, mentioned like preceding text, can comprise about the one or more indication in above incident and the condition by the represented characteristic of data.For instance; The audio frequency correlated characteristic can comprise the noise level of audio frequency, and the audio frequency correlated characteristic can comprise the comfort level of audio frequency to people's ear, and the heartbeat correlated characteristic can comprise the heart rate that is calculated; The pressure correlation characteristic can comprise the pressure value that is calculated; Temperature-dependent characteristics can comprise the temperature value that is calculated, and the oxygen concentration correlated characteristic can comprise the oxygen concentration value of being calculated, and the glucose level correlated characteristic can comprise the glucose level value of being calculated; Temperature-dependent characteristics can comprise the temperature value that is calculated, and the velocity correlation characteristic can comprise the velocity amplitude and the acceleration correlated characteristic that are calculated can comprise the accekeration that is calculated.
And for example preceding text are discussed, and in certain aspects, unloading is handled and can be improved by in the represented characteristic of data at least one.For instance, improving the audio frequency correlated characteristic can comprise the noise that reduces in the audio frequency or improve the comfort level (for example, add sidetone) of audio frequency to people's ear.Improve biological correlated characteristic and can comprise the calculating (for example, improving the accuracy of calculating) that improvement is used for confirming heart rate, blood pressure etc.Improve the surrounding environment correlated characteristic and can comprise the calculating (for example, improving the accuracy of calculating) that improvement is used for confirming pressure, speed etc.
In certain aspects, but processor 110 deal with data and further reduce device 102 desired processing promoting the transmission of auto levelizer 102 under some situations.For instance, wave coder 126 can provide the treated data that are through the waveform coding form (for example, through pulse code modulation data or through ∑-Δ modulating data).These data can be transferred to device 102 subsequently and need not any further processing (for example, compression) except that the standard transmission relevant treatment.Therefore, opposite with the treated data of expression waveform, device 104 also can be transferred to device 102 with Wave data.To discuss like hereinafter, under this kind situation,, therefore can carry out less processing at device 102 places because device 102 is the data of the form that can be easy to be provided to output device with reception.
After deal with data, device 104 sends to suitable destination with data.For instance, the LAN of device 104 or wide area network traffic assembly 128 can send to another device (for example, to the Wide Area Network of for example cellular network or to the internet, not shown among Fig. 1) via the suitable communication link with treated data.
Such as preceding text argumentation, device 104 can send it back treated data device 102.For instance, device 102 for the end user's of data situation under or device 102 be more suitable in treated data forwarding under the situation of final destination, install 104 and can treated data be sent it back device 102.Here, the transmission plan that optionally uses on the apparent link 106 of processor 110 and come coded data surely and will be provided to transmitter 130 through coded data subsequently.
The receiver 132 of device 102 can be provided to processor 108 to be used to the relevant treatment of communicating by letter with the data that received subsequently.For instance, the transmission plan that optionally uses on the apparent link 106 of processor 108 and the fixed data of decoding and being received.
Can how to implement the unloading processing in order to further specify; Will device 104 comprise the wireless device of mobile phone for example or entertainment device (for example, audio player) and install 102 comprise the embodiment of the telephone headset that is used for wireless device situation discusses the instance of unloading processing tout court.Under this behaviour in service, can various types of processing be unloaded to device 104 from telephone headset 102.For instance, in some embodiments, can be desired for telephone headset 102 provides echo elimination or active noise removing.Here, input unit 116 can comprise the microphone of sensing surrounding environment sound.Thereby telephone headset 102 can such as preceding text argumentation original sensing surrounding environment voice data (for example, waveform) is transferred to device 104.
Through understanding the preceding text summary, combination Fig. 2 A, Fig. 3 and Fig. 4 are discussed the additional detail of incorporating the system that unloading processing and operations associated are arranged in more detail.The exemplary components of Fig. 2 A illustrative system 200, said system 200 comprises wireless peripheral unit 202 and wireless device 204, it can be similar to wireless device 102 and wireless device 104 respectively in aspect one or more.Fig. 3 is about being transferred to data the operation of another device through execution from the device that produces sense data with (for example).Fig. 4 is about being transferred to data the operation of another device of dateout through execution from a device with (for example).For simplicity, the operation of Fig. 3 and Fig. 4 (or discussing among this paper or any other operation of teaching) can be described to carried out by specific components (for example, system 200).Yet, should be appreciated that said operation can be carried out and can be used the assembly of different numbers to carry out by the assembly of other type.Should also be clear that and in given embodiment, can not use one or more in the operation of being discussed in the wooden literary composition.
Fig. 2 A tracing device 202 is the instance of the peripheral unit of wireless device 204.For instance, wireless device 204 can comprise the air station of communicating by letter with one or more other devices (for example, WAP).In some embodiments, wireless device 204 can comprise mobile phone.Under this kind situation, peripheral unit 202 can comprise (for example) for example ancillary equipment of telephone headset, watch, medical treatment device or a certain other appropriate device.Should be appreciated that and in this paper, the variety of way the specific description to implement the teaching among this paper.Therefore, in other embodiments, device 202 can not be a peripheral unit.
Fig. 2 A is the instance that communicates via the air interface that is used for human body local area network network or personal area network of tracing device 202 and 204 also.Yet, should be appreciated that device 202 and 204 can use the communication link of other type to communicate.
Existing referring to Fig. 3, in certain aspects, unloading is handled and can be installed the situation that receives data and represent said another apparatus processes data subsequently from another about a device.As represented by square frame 302, the input translator 206 (for example, transducer) of device 202 produces the data corresponding to transducer type among Fig. 2 A.For instance; In some embodiments; Converter 206 can be suitable for sensing, and for example aural signature is (for example; Sound, audio frequency, voice or music), the multimedia characteristic of both or both the above a certain combination in visual signature (for example, the for example rest image of picture or the for example mobile image of video) or the said characteristic to be to produce multi-medium data.In some embodiments, converter 206 can be suitable for the biological correlated characteristic of for example heartbeat of sensing, blood pressure, body temperature, oxygen concentration levels, G/W equality.In some embodiments, converter 206 can be suitable for the for example surrounding environment correlated characteristic of pressure, temperature, speed, acceleration etc. of sensing.
In certain aspects, the sense data that is produced by converter 206 is the form of analogue data.This analogue data can be represented (for example) continuous wave (for example, voice data), discontinuous waveform (for example, heartbeat) or more discrete in essence information (for example, pressure, speed etc.).
As represented, install 202 preliminary treatment sense datas to be used for transmission by square frame 306.Such as preceding text argumentation, in some embodiments, preliminary treatment can relate to waveform coding institute sensed data (the original analog data of for example, being exported by converter 206).Here, wave coder 210 can be carried out the for example operation of the waveform coding of ∑-Δ modulating-coding, pulse code modulated coding or some other appropriate formats.Through converting analogue data into digital form, can easily transmit original waveform data via the communication link that utilizes Digital Transmission.
Here, should be appreciated that and to send data via communication link by high relatively data rate.For instance, be not that compressed data is sent to device 204, but can send data through overall pulse sign indicating number modulation format or to cross sampled form (for example, through ∑-Δ modulating data).Therefore, the routine techniques of the data that received with packed data before sending data via communication link (for example, use sub-band coding ins conjunction with bluetooth, MP3, or stereo coding) and decompression is compared, and the method that is disclosed can relate to less processing.For instance, for transmission, routine techniques can be with converting into through pulse code modulation data through ∑-Δ modulating data and can before the transmission data, compressing through pulse code modulation data.On the contrary, receiving terminal can relate to decompressed data to provide through pulse code modulation data or will convert into through ∑-Δ modulating data through pulse code modulation data.
Possibly need more wireless bandwidth although compare the method that is disclosed with the method for using compression, especially can the application of using relative high-bandwidth communication channel, can more effectively transmit data application or both all can application in realize favourable compromise.For instance, in the application of using the ultra-wideband communications ultra broadband of pulse (for example, based on), realize favourable compromise.
The use of ∑-Δ modulation also can promote the more reliable transmission of data via Radio Link.For instance, suppose that in ∑-Δ modulation signal each is actually least significant bit, can not have appreciable impact to institute's data recovered then for during the transmission losing of location.On the contrary, sending in the scheme of overall pulse sign indicating number modulating data (for example, 16 PCM) via link, losing of any one in the higher significance bit can have remarkable adverse effect to institute's data recovered.
But device 202 also preliminary treatment institute sensed data is to promote the reliable transmission via communication link.For instance, transmission pre-processing assembly 211 can provide chnnel coding, error-coded, scrambling, interlock, formats or other similar signal processing.
As represented by square frame 308 and 310, transmitter 212 will be transferred to the receiver 214 of device 204 through pretreated data via wireless communication link.Device 204 can carry out subsequently some preliminary treatment complementary processing of carrying out with square frame 306 places with recover to produce in square frame 306 places through the waveform coding data.For instance, one or more processors 216 of device 204 can be carried out channel-decoding, error decoding, separate scrambling, release of an interleave, separate format or other similar operations.
As represented by square frame 312, on behalf of device 202, the processor 216 of device 204 can handle the data that received subsequently.For this reason, processor 216 can extract by at least one represented characteristic of the analogue data of institute's sensing.Such as preceding text argumentation, this can relate in fact from the data reconstruction original analog data that received (for example, producing the data that the expression original waveform adds quantizing noise).For instance, on behalf of device 202, processor 216 can derive through ∑-Δ modulating data, through pulse code modulation data or subsequently will be through the analogue data of further processing.

The unloading processing can be implemented in every way and be used to support various functional.In some embodiments, device one in 202 and 204 or both can optionally provide extra process.In some embodiments, said processing only will can be unloaded to device 203 by the part that device 202 is carried out originally.In some embodiments, can dynamical fashion carry out about whether unloading the decision-making of processing.Fig. 2 B illustrative system 200B, said system 200B have and comprise device 202B and the 204B that can be used for the some assemblies in the for example described embodiment.Substantially, Fig. 2 B assembly with or like symbol identical with Fig. 2 A assembly also can have identical or similar functions property.
Such as preceding text argumentation, in some embodiments, the non-transmission relevant treatment of all of institute's sense data can be unloaded to wireless device 204.Yet in some embodiments, some are handled still and can be carried out by device 202.Therefore, shown in Fig. 2 B, in certain aspects, device 202B can optionally comprise the processor 208 that is used to handle institute's sense data.
And for example preceding text are discussed, and in some embodiments, all non-transmission relevant treatment that are sent to institute's sense data of device 202 can be unloaded to wireless device 204.Yet in some embodiments, some processing still can be carried out by peripheral unit.Therefore, shown in Fig. 2 B, in certain aspects, device 202B can optionally comprise the processor 230 that is used to handle the data that received.
In some embodiments, device 202B can carry out some processing and other processing is unloaded on the device 204B.For instance, device 202B (for example, telephone headset) can have about MP3 decompression, echo elimination and the aborning one or more disposal ability of sidetone (for example, being provided by processor 230).As represented by line 246, processor 230 can receive some the information that is used in this processing (for example, sidetone produces) from input translator 206.In addition, device 204B (for example, mobile phone) can comprise that disposal ability is to provide one or more in the said operation.For instance, one or more processors 216B can comprise MP3 decompressor 248, sidetone processor 250 or echo eliminator 234.Therefore, look the requirement of given application and decide, device 202B and 204B can make device 204B treat one or more from the operation of device 202B unloading with execution from device 202B receiving sensor data through configuration.
In some embodiments, can the dynamical fashion unloading handle.For instance, device 202B can detect device 204B and has in order to carry out the ability with the operation of the executable operation of device 202B (for example, MP3 decompress etc.) same type.Therefore, as long as device 202B communicates by letter with device 204B, then install 202B and can break off its circuit or inactive its processing functional and operative installations 204B.Therefore, when operating alone, device 202B can provide and himself handle (for example, crossfire does not have MP3 decompression ability from the MP3 music of quickflashing softdog (FLASH dongle)).In addition; If the electric charge on the battery of device 204B drops to below the critical point, then install 204B and can stop to provide unloading to handle (for example, decompression MP3 data) and alternately (for example untreatment data; MP3 data through compression) send to device 202B, install 202B by this and will carry out processing.Under another behaviour in service; Device 202B (for example; The heart rate monitor transducer) can be at first treated sensing data (for example, measured heart rate) be sent to second device (for example, device can be the only watch of display message) with unloading relevant treatment ability.Subsequently, At All Other Times a certain, the device 202B can with untreated sensing data (for example, heartbeat waveform) send to have suitable disposal ability (for example, heart rate detection) another the device 204B (for example, mobile phone).
On behalf of wireless device 202, the wireless device 204 of Fig. 2 A can carry out various types of operations.Fig. 5 explanation can provide the exemplary components in the embodiment of the some or all of signal processing that need carry out the data of being exported by wireless device 504 (for example, it can be similar to device 202) at wireless device 502 (for example, it can be similar to device 204).Here, the form that device 502 can Wave data sends to device 504 with treated data.Therefore, device 504 can only be provided to the for example suitable output device of converter with the Wave data that is received.
With the similar fashion like preceding text, device 502 can comprise communication processor 506, and said communication processor 506 can (for example) receive data via LAN, Wide Area Network or a certain other communication link.Communication processor 506 can optionally be handled (for example, decoding) data that received and go to the data of device 504 with extraction.
The gained data are provided to can represent device 504 data processor for processing data 508.Data processor 508 can comprise data decompressor 510, and said data decompressor 510 is decompressed data under the situation of the previous warp compression of data.In addition, data processor 508 can comprise processor 512, and said processor 512 for example can provide the signal processing function property of (for instance) decoding.In certain aspects, signal processing also can attempt to improve as institute's teaching among this paper by at least one represented characteristic of data.
In certain aspects, processor 512 can provide waveform processing functional to produce through the waveform coding data.For instance, with the similar fashion of being discussed like preceding text, processor 512 can produce through pulse code modulation data, through ∑-Δ modulating data or a certain other form through the waveform coding data.
At device 504 places, receiver 518 is handled the data (for example, the similar fashion to be discussed like preceding text) that receive via link 516.Provide in the embodiment of waveform coding data at device 502, receiver 518 is exportable through the original waveform coded data.Waveform processor 520 can optionally handle subsequently received be provided to proper transformation device 522 (for example, loud speaker) through the waveform coding data and with said data.
In certain aspects, waveform processing can be advantageously used in and reduce device 504 needed treating capacities and install 504 power that consume.For instance, waveform processor 520 and converter 522 can comprise universal amplifier, D class A amplifier A or direct drive-type D class A amplifier A.Perhaps, in some embodiments, ∑-Δ data can be delivered to general D class A amplifier A unprocessedly.With combining Fig. 6 and Fig. 7 to discuss an embodiment of direct drive-type D class A amplifier A circuit in more detail.
The exemplified aspect of the output translator circuit 600 that Fig. 6 explanation can directly be driven by the Wave data that is received 602 (for example, through ∑-Δ modulating data).Here; Output translator circuit 600 comprises direct drive-type D quasi-controller 604; Said direct drive-type D quasi-controller 604 produces and (for example is used to control pair of switches 608A and 608B; Transistor) control signal 606A and 606B saidly drive output translator 610 (for example, optionally via low pass filter 612) again to switch.In certain aspects, directly drive-type D quasi-controller 604 can produce control signal 606A and 606B based on the difference of the duration that is associated with the Wave data 602 of varying level.For instance, referring to Fig. 7, what the generation time of control signal Q1 and Q2 (for example, control signal 606A and 606B) and width can be based between one and zero width of the continuous level among ∑-Δ modulation waveform data S (for example, Wave data 602) is poor.Therefore, the Wave data 602 that is received is driving transducer 610 and without undergoing for example attempting to improve the processing that converts analogue data by the processing of the signal processing of the represented characteristic of data or with Wave data into directly.Through getting rid of this signal processing, wireless device (for example, device 504) is compared with the conventional equipment of not carrying out this signal processing and can be consumed less power.
Referring to Fig. 6 and Fig. 7, will study the additional detail of the generation of control signal 606A and 606B once more at present.In some embodiments, control signal Q1 and the Q2 interval generation that can be associated in set with the continuous high level part (for example, having value " 1 ") of Wave data S and low level part (for example, having value " 0 ").Define an instance of the said set of continuous high level and low level part by the represented time cycle of line w0, w2 and w4.Time cycle w0 comprises time cycle P0 and P1, and wherein Wave data S is made up of succeeded by three continuous low level pulses five continuous high level pulses respectively.Likewise, time cycle w2 comprises time cycle P2 and P3, and wherein Wave data S is made up of four continuous high level pulses and five continuous low level pulses respectively.In addition, time cycle w4 comprises time cycle P4 and P5, and wherein Wave data S is made up of seven continuous high level pulses and three continuous low level pulses respectively.
In the instance of Fig. 7, control signal Q1 and Q2 are based on the pulse of time cycle w0, w2 and w4 and produce.Specifically, under the situation of high level pulse number greater than the low level pulse number of said time cycle in cycle preset time (for example, time cycle W0), can produce negative-going pulse to signal Q1.On the contrary, under the situation of high level pulse number less than the low level pulse number of said time cycle in cycle preset time, can produce direct impulse to signal Q2.Therefore, in the instance of Fig. 7, after time cycle W0 and w4, on signal Q1, produce pulse, and after time cycle W2, on signal Q2, produce pulse.
In certain aspects, the width of control impuls Q1 and Q2 is based on the pulse of time cycle W0, W2 and W4.For instance, the width of control signal can be based on poor between high level pulse number and the low level pulse number mouthful in cycle preset time.Therefore, in the instance of Fig. 7, because time cycle P0 has five high level pulses and time cycle P1 has three low level pulses, so first pulse of control signal Q1 has the width of two pulses.Likewise, because time cycle P2 has four high level pulses and time cycle P3 has five low level pulses, therefore the pulse of the control signal Q1 after time cycle W2 has the width of a pulse.
Above embodiment advantageously provides the D type output that utilizes three-state control signal.For instance, equate that in continuous duration of the Wave data of level two control signals will be broken off under the situation of (for example, in the expression audio signal silent).Therefore, control signal can have the state of opening a switch, another state of opening another switch, and does not open the another state of arbitrary switch.Through using this tristate technique, the power consumption of circuit 600 is can be in fact proportional by the volume and the significant level of the represented audio signal of Wave data 602 with (for example).
Should be appreciated that control signal Q1 and Q2 can produce based on other sequential relationship.For instance, in some embodiments, control signal Q1 and Q2 can produce based on the pulse collection that is associated with time cycle w1, w3, W5 etc.In addition, in some applications, control signal Q1 and Q2 can produce based on even number time window (w0, w2, w4 etc.) and odd number time window (w1, w3, w5 etc.), and the pulse output number on Q1 and the Q2 is doubled.Here, the collision between effective Q1 and Q2 pulse maybe be more frequent; Therefore, but the precompose arrangement to guarantee not open simultaneously switch.
Can implement in every way to provide to be similar to and discussed functional direct drive-type D class A amplifier A circuit or a certain other similar circuit with preceding text.For instance, in some embodiments, controller 604 can comprise pulse counter 614, the pulse number that said pulse counter 614 countings are associated with the Wave data 602 of each level.The gained counting can be sent to control impuls generator 616 subsequently, and said control impuls generator 616 produces control signal 606A and the 606B that discusses like preceding text.In some embodiments, the up/down counter can be used for confirming one and zero number difference in the continuous level of Wave data 602.Under this kind situation, the gained count value can be passed to another counter, and said counter counts downward produces control signal 606A and 606B by this with the pulse of output proper width.In certain aspects, output stage (for example, comprising switch 608A and 608B and converter 610) alternately comprises the H bridger, and said H bridger comprises two pairs of switches, and wherein each is coupled to the unique person in two input terminals of converter 610 to switch.
Such as preceding text argumentation, in some embodiments, Wave data can comprise through the multidigit pulse code modulation data.Under this kind situation, controller 604 can comprise ∑-Δ modulating coder, and said ∑-Δ modulating coder will convert into through ∑-Δ modulating data (for example, the Wave data S of Fig. 7) through pulse code modulation data.
Teaching among this paper can be used with the pulse-width modulation scheme of other type.For instance, circuit 600 can be suitable for handling the Wave data (data that for example, in time quantize) of taking multimode more to intend form.Therefore, controller 604 can be suitable for based on the pulse duration of Wave data 602 but not step-by-step counting (for example, " 1 " reaches " 0 ") produces control signal 606A and 606B.
Wave data can be represented any one in the various types of information.For instance, Wave data can be represented audio signal, various forms of sensing signal, RF signal or a certain other adequate information (for example, such as preceding text argumentation).
