提出了一种将PSpice的参数扫描分析和优化分析结合起来对电路进行最优化设计的新方法,即先用参数扫描分析实现电路的次优化设计,再用优化分析实现电路的最优化设计。给出了应用该方法实现带通滤波器电路最优化设计的流程和仿真结果,实验结果表明滤波器电路的最优化设计不仅能完全满足性能指标的要求,而且还可以降低优化迭代运算和仿真执行的次数,提高优化设计的效率和准确性,同时也验证了该方法对电路进行最优化设计是有效和可行的。

A novel method is proposed by concatenating parametric sweep analysis with optimizing analysis based on PSpice, Sub-optimization is realized by parametric sweep analysis, and then optimization is done by optimizing analysis. The implemental steps and processes are illustrated in designing band pass filter circuit. The simulation results show the proposed novel method can not only meet the design target specifications completely, but also reduce iterative and simulative number, enhance efficiency and accuracy. The method is very effective and valid for optimizing electronic circuit design.
