Abstract
Gain and timing mismatches among sub-converters limit the performance of time-interleaved analog-to-digital converters (TIADCs). In this paper we present a blind adaptive method, based on the least-mean-square (LMS) algorithm, to compensate gain and timing mismatches in TIADCs. Similar to other methods in the literature, we assume a slightly oversampled input signal, but, contrary to them, we can apply our method to an arbitrary number of channels in a straightforward way. We give a detailed description of the compensation and the identification part of the method and demonstrate its effectiveness through numerical simulations.
