Methods and apparatus for an analog-to-digital converter (ADC) with reduced comparator-hysteresis effects. One embodiment uses a charge-redistribution ADC. One method performs an initial coarse analog-to-digital conversion to avoid overdriving an analog voltage comparator. One such method includes a...http://www.google.de/patents/US5675340?utm_source=gb-gplus-sharePatent US5675340 - Charge-redistribution analog-to-digital converter with reduced comparator-hysteresis effects
