Abstract

Time-interleaved analog to digital converter (TI-ADC) is a technique of increasing sampling frequencies and bandwidth while keeping high resolution. In this paper, the authors aim to characterize a TI-ADC with mismatches. They propose equivalent scheme and identification to timequantized pseudorandom sampling technique. The goal of this identification is to enable the adaptation of mismatch compensation technique of TI-ADC to recover mismatches in ADC acquisition using timequantized pseudorandom sampling.
