| Abstract: | In this article, an analytical approach, for optimum nonlinear circuit analysis is described. At a given input frequency, the method consists in determining, for each nonlinear component of the circuit, a closed volume including all the allowed powers at its terminal ports. The boundary of this volume, called “characteristic surface,” allows extremum powers of nonlinear devices to be predicted and then optimum performance of the circuit to be deduced. Applied to various microwave transistor circuits, this procedure has shown good agreement between computed and measured or previous published results. © 1996 John Wiley & Sons, Inc. |
