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.

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.File in questo prodotto:
