Analysis of nonlinear RF and microwave circuits using harmonic balance and system identification methods

The use of harmonic balance standard simulations and system identification methods to analyze the nonlinear behavior of high-frequency circuits is reported. In order to illustrate the technique, two circuits are analyzed and measured: an oscillator and a monolithic digital frequency divider by two. Both circuits show different operating modes. © 2002 Wiley Periodicals, Inc. Int J RF and Microwave CAE 12, 448–459, 2002. Published online in Wiley InterScience (www.interscience.wiley.com).
