摘要
本文介绍了如何应用PSpice仿真软件辅助设计"模拟电子技术"课程中有源低通滤波器这一难点内容。给出一阶和二阶有源低通滤波器的传递函数及电路参数的计算方法。本文通过一个项目实例进行电路结构选择、阶数计算和PSpice电路仿真,设计出五阶巴特沃斯低通滤波器。电路的测试结果与仿真结果基本一致,最后还对电路的噪声进行分析。
This paper describes the design method for active low-pass filter of Analog Electronics Technology course teaching by using PSpice electronics circuit simulation software.This paper introduces the transmission function and parameters calculation of first-order,second-order active low-pass filter.In order to satisfy the requirement of one project,it is important to select circuit architecture,calculate the number of order,design five-order Butterworth low-pass filter and using PSpice software to simulate the design of circuit.The circuit parameters of measurement are consistent with simulation results and noise analysis is described in the paper.
