提出了一种不仅能优化电路元件参数,还能优化电路结构的优化电路设计的新算法。在被优化的电路元件参数发散时,本算法能自动地修改电路结构,使优化过程能继续进行;当参数优化收敛,但目标函数仍不满足预定要求时,可以自动地增加一些元件,从而改进目标函数值。根据这一算法用FORTRAN语言编制的优化程序,在Dual-68000微机上对晶体管的等效电路进行了优化处理,得到了更为接近实测特性的等效电路,从而证明了本算法的有效性。 A new algorithm is proposed to optimize circuit design which not only optimizes the parameters of circuit components, but also optimizes the circuit structure. When the optimized parameters of circuit components diverge, the algorithm can automatically modify the circuit structure, so that the optimization process can continue; when the parameters converge, but the objective function still does not meet the predetermined requirements, some elements can be automatically added to improve The objective function value. According to the optimization algorithm compiled by FORTRAN in this algorithm, the equivalent circuit of the transistor is optimized on the Dual-68000 microcomputer, and the equivalent circuit which is closer to the measured characteristic is obtained, which proves the effectiveness of the algorithm.
