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.
Journal ArticleDOI
Floating-point error analysis of recursive least-squares and least-mean-squares adaptive filters
TL;DR: In this paper, a floating-point error analysis of the RLS and LMS algorithms is presented, where the expression for the mean-square prediction error and the expected value of the weight error vector norm are derived in terms of the variance of the floating point noise sources.
Journal ArticleDOI
Table-based modeling of delta-sigma modulators using ZSIM
TL;DR: ZSIM integrates analytic tools, a difference equation simulator, a table-based nonlinear Z-domain simulator, and digital signal processing into a workstation environment to provide fast and accurate simulation of delta-sigma modulators.
Journal ArticleDOI
Table-based simulation of delta-sigma modulators
TL;DR: In this article, the benefits and limitations of a table-based approach to the simulation of delta-sigma modulators with switched-capacitor integrators are explored, as well as simulations demonstrating the importance of using an accurate and charge-conservative circuit simulator for table point transient simulations.
Printed circuit board layout verification and circuit extraction
TL;DR: The work is aimed at determining approaches to post layout netlist extraction for printed circuit board simulation taking in to account proximity effects such as coupling of traces and EMI.
