Abstract :
In this paper, an effective digital self-calibration method for time-interleaved parallel pipeline ADCs is presented. The method corrects errors of MDACs within the channel ADCs and compensates gain and offset mismatches between parallel channels. According to simulations, 14-bit accuracy can be achieved with 10-bit device matching.
