摘要
A digital-domain self-calibration technique for video-rate pipeline AID converters based on a white Gaussian noise input signal is presented The implementation of the proposed algorithm requires simple digital circuitry. An application design example of the self-calibration of a 12b, 40 MS/s CMOS pipeline ADC is shown to illustrate that the overall linearity of the ADC can be highly improved using this technique.
