Abstract

This paper presents an improved cavity model for the analysis of transient voltage bounces in power/ground structures. Firstly, accurate models from DC to the maximum frequency of interest are adopted to describe conductor and dielectric losses; secondly, the Vector Fitting technique is used to generate a rational model which is converted in a state-space macromodel, well suited for transient analysis. The numerical results demonstrate the high efficiency and good accuracy of the proposed method.
