Abstract

The implementation of extensive optimization capabilities in a general-purpose harmonic-balance simulator is described. Two different optimizers suitable for autonomous and forced circuits, respectively, are discussed in detail, and their merits and limitations are compared. The efficient numerical optimization of nonlinear microwave circuits specified over a finite frequency band is demonstrated. An example is given, showing that the procedure is very efficient, thus opening the way to the straightforward design of some modern monolithic microwave integrated circuit (MMIC) devices such as multioctave distributed mixers and power amplifiers.<>
