Abstract

Mismatch-shaping Dynamic Element Matching (DEM) methods are extensively used in multi-bit Sigma-Delta Modulators (SDM) to reduce the effects of element mismatches. To date, only first and second-order mismatch-shaping DEM techniques have been reported in the literature. In this paper, a higher-order mismatch-shaping DEM method is reported, which is an extension of the known vector-feedback mismatch-shaping technique. Example simulation results are presented for thirdorder and fourth-order mismatch-shaping DEMs.
