Modeling memory effects in nonlinear subsystems by dynamic Volterra series

Abstract

Design challenges resulting from single chip integration of RF and microwave transceivers is requiring both more powerful analog simulation techniques and more accurate behavioral models that allow efficient hierarchical simulation. Today system level models are limited by their inability to effectively cope with nonlinear memory effects. We describe a modeling approach based on modified Volterra series, which accounts efficiently for memory effects in nonlinear subsystems.
