一,概述 所谓电子线路的优化设计,就是利用计算机自动调整电路元件参数,使其响应达到设计要求。目前,机助优化设计的常用方法是: 首先提出一个作为设计要求的数学模型-目标函数(它是电路的实际响应与设计要求之间误差的量度)。 其次给出电路方案,确定设计变量(即给定电路拓朴、元件类型和初始值)作为机辅设计的起始点。 First, an overview of the so-called electronic circuit optimization design, is the use of computer automatically adjust the circuit component parameters to meet the design requirements. At present, a common approach to machine-assisted optimization design is to first propose a mathematical model as a design requirement-the objective function, which is a measure of the error between the actual circuit response and the design requirements. Second, the circuit scheme is given, and the design variables (ie, given circuit topology, element type and initial value) are determined as the starting point of the machine-aided design.
