A method and circuit for gain and/or offset correction in a CDAC circuit are provided. The gain and/or offset correction can be realized by adjusting the sampling capacitance of a capacitor array, with a positive array of the CDAC circuit being trimmed for gain correction, and a negative array of the...http://www.google.de/patents/US6922165?utm_source=gb-gplus-sharePatent US6922165 - Method and circuit for gain and/or offset correction in a capacitor digital-to-analog converter
