摘　　要：简述电路进化设计的基本原理和发展现状。针对制约进化设计速度和规模的主要因素,提出并讨论一种基于典型电路结构、PSPICE仿真和遗传参数自适应的改进方法。有源滤波器等的进化实验结果表明,该方法支持对元件参数和电路结构的同时进化,并可显著加快进化速度。Basic principles and key problems of evolutionary design of electronic circuits are briefly introduced. A novel approach is proposed to improve the design efficiency and reduce the circuit size remarkably under current condition. This approach starts with a typical topology of the target circuit,evaluates the fitness by PSPICE simulation, and accelerates convergence by genetic parameters adaptation. A series of successful experiments involving the evolutionary design of active filters demonstrate that with means of this approach, evolution of component sizes and structure of the target circuit can be evolved simultaneously, and the design process can be accelerated considerably.

关 键 词：电路进化设计 遗传参数自适应 可进化硬件
