Binary Sequences With Good Spectral Properties Obtained by Genetic Algorithms
TL;DR: A novel method for the digital synthesis of high quality signals by means of one-bit digital-to-analog converters and the individuation of the best binary sequences for signal generation and the analysis of their properties is described.
A methodology for characterizing and introducing MOSFET imperfections in analog top-down synthesis and bottom-up validation
TL;DR: In this article, a measurement-based analog ID card is developed to optimize the analog performance and reliability at high temperature by enabling the choice of optimal process (bulk vs. partially-depleted silicon-on-insulator (SOI) vs. fully-deleted SOI), optimal devices (e.g., multi-threshold voltages process) and optimal bias (weak vs. moderate vs. strong inversion).

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.

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.
