Abstract :
A new analysis method for nonlinear circuits is presented. By representing nonlinear components with one- or two-dimensional series of orthogonal polynomials, circuits are analyzed solely in frequency domain. Improvement in computing efficiency is such that microwave circuits with multiple independent excitation frequencies can be analyzed on a microcomputer. As an example, intermodulation analysis of a MESFET mixer is presented.
