A 101-dB SNR hybrid delta-sigma audio ADC using post integration time control
Moo-Yeol Choi,Sung-No Lee,Seung-Bin You,Wang-Seup Yeum,Ho-Jin Park,Jae-Whui Kim,Hae-Seung Lee +6 more
TL;DR: A post integration time control (PITC) technique is proposed for calibration of the RC time constant variation of the continuous-time integrator and a jitter insensitive pulse generator (JIPG) circuit overcomes the degradation of SNR due to the feedback DAC clock jitter.

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.
Journal ArticleDOI
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.

The Structure of Quantization Noise from Sigma-Delta Modulation
James C. Candy,O. Benjamin +1 more
TL;DR: Simple algebraic expressions for this modulation noise and its spectrum in terms of the input amplitude are derived and can be useful for designing oversampled analog to digital converters that use sigma-delta modulation for the primary conversion.
