摘　　要： 概述了积分器和滤波器的工作原理,对这两种含运放典型电路的应用计算方法进行了说明,推导了输入/输出关系表达式,并采用Proteus仿真软件进行了仿真验证。结果表明,软件仿真与理论计算结果一致。给出了一种电压反馈取样电路的详细设计方法,该电路可以较好地反映输入信号的变化。针对滤波器快速设计方法中相位计算繁琐的不足,指出通过软件仿真可以准确、快捷地得出补偿量。 The working principles of integrator and filter are summarized. The computation method of typical circuit with operational amplifier is described. The input and output expressions are deduced and are verified by Proteus simulation software. It indicates that the result obtained by the software simulation is identical with that of the theoretical calculation. A de- tailed design method about a sample circuit of voltage feedback is explained. The variation of the input signal can be better reflected by the circuit. Aiming at the shortcoming of phase calculation when the method of the filter quick design is adopted, it is pointed out that the compensation quantity can be achieved accurately and quickly by software simulation.
