摘要 在任意系数求和运算放大电路的设计中,输入电阻和实现所要求的运算关系往往不能同时满足要求,使此类电路的设计让人感到很复杂,甚至无从下手。通过对反相端输入信号的加权系数RR1F和同相端输入信号的加权系数RR2F的讨论,给出改进的电路形式和设计的方法,可以满足求和运算电路输入端电阻平衡和实现所要求和的运算关系。 In operational circuit of realizing summation, operational circuit of realizing summation often can not meet the needs to enlarge circuit input resistance and realize the operation relationship demanded meanwhile,the circuit design of such people is very complex,even impossible to start. Based on the reverse side of the input signal RF/R2 and the same coefficient of the input signalweighted coefficient RF/R2 of discussion. This paper provides the improved circuit shape and method to design, which can achieve resistance balance of its input terminal and realize there quied operational condition.
