Abstract
A new parallel time-interleaved architecture for a two-path second-ord er switched-capacitor (SC) sigma-delta modulator is presented. This st ructure allows doubling of the oversampling sampling ratio (OSR) and, in addition, leaves an idle clock phase available for compensation of nonidealities. Simulations show that the presented architecture has a low sensitivity to path mismatch.
