An improvement to the harmonic-balance technique for analyzing nonlinear circuits
- 27 Downloads
In this paper, an improved method, which is based on the harmonic-balance technique, for speeding up the convergence iteration procedure is presented. As an example, it is applied to the nonlinear analysis of microwave mixer, in which a simple time domain to frequency domain transformation technique for the mixer diode is firstly introduced. The use of this technique saves computing time dramatically. And the analyzed results are in good agreement with the results published. The improved method can also be extende to the CAA of nonlinear circuits with multi-devices.
