Analyzing Strongly Nonlinear Multitone Circuits by Multi-Time Methods
Analyzing Strongly Nonlinear Multitone Circuits by Multi-Time Methods Jaijeet Roychowdhury Bell Laboratories, Murray Hill, USA jaijeet@research.bell-Iabs.com Abstract Harmonic balance and traditional time-domain simulation techniques are limited in their applicability when strong nonlinearities and multi-tone signals are both present. In this paper. new simulation algorithms are described and use
