分析非線性電路的諧波平衡法的改進(jìn)
AN IMPROVEMENT TO THE HARMONIC-BALANCE TECHNIQUE FOR ANALYZING NONLINEAR CIRCUITS
-
摘要: 本文根據(jù)分析微波非線性電路的基本方法之一諧波平衡法,提出了一種加速收斂過(guò)程的改進(jìn)方法,并且將其應(yīng)用于微波混頻器的非線性分析。在分析過(guò)程中引入了混頻二極管非線性特性由時(shí)域到頻域的簡(jiǎn)化變換技術(shù),大大加快了計(jì)算速度。分析結(jié)果與已發(fā)表的結(jié)果相比較,一致性較好。這種改進(jìn)的分析方法也可以推廣應(yīng)用于包含多個(gè)非線性器件的非線性電路的計(jì)算機(jī)輔助分析。

Abstract: An improved method, which is based on the harmonic-balance technique, for speeding up the convergence of iteration procedure is presented. As 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 introducel. The use of this technique saves computing time dramatically. And the analyzing results are in good agreement with the results published. The improved method can also be extended to the CAA of nonlinear circuits with multi-devices. -
