A Novel Approach for Evolutionary Design of Circuits Based on Typical Topology and Adaptive Genetic Gperations
Shuguang Zhao · Journal of Circuits and Systems · 2003
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.
