Negative feedback influence on simultaneous switching CMOS outputs

Abstract

Recent studies indicate that CMOS circuits exhibit nonlinear behavior (due to the negative feedback) of ground noise as a function of the number of signals switching. Electrical network formulation, modeling and simulation of simultaneously switching signals are discussed. Detailed equations, models, and transient characteristics are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
