Advanced time-domain techniques for strongly nonlinear RF circuit simulation: Recent developments and remaining challenges

Simulating modern wireless communication systems is today a hot topic. Serious difficulties arise when these systems are composed of strongly nonlinear highly heterogeneous circuits operating in multiple time scales. In this sense, this paper provides a general overview on the existing time-domain s...

Description
Summary:Simulating modern wireless communication systems is today a hot topic. Serious difficulties arise when these systems are composed of strongly nonlinear highly heterogeneous circuits operating in multiple time scales. In this sense, this paper provides a general overview on the existing time-domain simulation techniques, as the ones encountered in commercial packages, or the ones recently published in the literature. Some new results will be introduced by presenting a comparison between the most relevant univariate and multivariate time domain techniques, in terms of computational efficiency.
