A differential quantizer-based error feedback modulator intended for digitizing analog signals and its comparison to the traditional interpolative sigma delta analog-to-digital conversion is presented in this brief. The differential quantizer-based error feedback modulator also falls under the class of noise-shaping data converters. This newly introduced technique replaces the integrator with a differential...
A dual extended noise shaping based time-interleaved symmetric cross-coupled sigma-delta modulator, which enhances the performance of conventional unextended and extended noise shaping based time interleaved cross-coupled sigma-delta modulator architecture, is proposed in this paper. The N-path first order cross-coupled sigma-delta modulator can attain only Nth-order noise shaping for unextented case...
