Design of A Low-Power-Consumption and High-Performance Sigma-Delta Modulator
TL;DR: Based on the switched-capacitor discrete time sampling technique in 0.18um CMOS technology, a modified single loop 3rd order sigma-delta modulator used for a resolution of 16bit sigma -delta ADC is proved to be robustness, the high performance in stability, anti- mismatch, chip area, and the power consumption is only 2.6mw when the power supply is 2.8V.

A higher order topology for interpolative modulators for oversampling A/D converters
TL;DR: Higher order modulators are shown not only to greatly reduce oversampling requirements for high-resolution conversion applications, but also to randomize the quantization noise, avoiding the need for dithering.

Decimation for Sigma Delta Modulation
TL;DR: It is shown that digital filters comprising cascades of integrate-and-dump functions can match the structure of the noise from sigma delta modulation to provide decimation with negligible loss of signal-to-noise ratio.

An analysis of nonlinear behavior in delta - sigma modulators
Sasan H. Ardalan,J.J. Paulos +1 more
TL;DR: This paper introduces a new method of analysis for deltasigma modulators based on modeling the nonlinear quantizer with a linearized gain, obtained by minimizing a mean-square-error criterion, followed by an additive noise source representing distortion components.
