Multi-Rate Methods for Simulating Electronic Circuits Driven by Envelope-Modulated Signals

Abstract:- In electronics many kinds of circuits with widely separated rates of variation are frequently found. Such situation usually takes a considerable dimension in telecommunications, like radio frequency or microwave applications. These are typical cases where multi-rate behavior may be found, due for example to envelope modulated excitations. In this paper some efficient methods for simulating circuits excited by this type of stimulus are presented and tested in an illustrative example. Key-Words:- Electronic circuit simulation, envelope-modulated signals, separated time scales.
