Abstract

Influence of channel error distribution on inter-channel mismatches of pipelined time-interleaved A/D converters (TIADCs) is discussed in this paper. TIADC systems can increase the maximum sample rate, but the mismatch between the channels significantly reduce the systems’ performance. This paper analyzes the mismatch in frequency domain, and discusses the influence of amplitude distribution of the inter-channel errors on the mismatch. Finally comes to a conclusion that when the error of one channel is equal to the median of the two adjacent channel errors, them is match of the overall TIADC system is minimal. According to simulation results, it can instruct a way to reduce the mismatch of TIADCs.
