误差反馈加抖型MASH 2-1-2结构Delta-Sigma调制器设计与实现
This paper presents the implementation of two digital noise-cancellation circuits (DNCCs) using a proposed algorithm and a Karnaugh map for a 2+1 multistage noise-shaping (MASH) delta-sigma modulator (DSM). The MASH architecture inherits a superior signal-to-noise-and-distortion ratio (SNDR) ...
This paper presents a novel Delta Sigma Modulator (DSM) in form of MASH 2-2-1, which can suppress the spurious tones in spectrum for all constant inputs and initial conditions. We can increase the order of noise shaping of the applied dither to that of the modulator without any spurious ...
