Abstract

The Letter describes the digital adaptive correction of nonidealities in dual-quantisation delta-sigma modulators. The sources and effects of nonidealities in a delta-sigma loop are discussed, and a simple on-line correction scheme is presented. The theoretical signal-to-noise ratio (SNR) improvement is calculated and simulation results are given which illustrate the effectiveness of the technique.
