Abstract

This paper introduces a structure for Compensation of dynamic nonlinear mismatches in time-interleaved analog-to-digital converter (TIADC). The basic idea of the proposed compensation structure is to reconstruct error signal and then subtract the reconstructed error from the output signal of TIADC. The compensation performance can be improved progressively by cascading compensation structure. We also proposed the real-valued compensation structure, which is suitable for implementation in hardware.
