摘　　要：提出一种基于WEBENCH软件的巴特沃斯低通滤波器的设计方法。分析了巴特沃斯低通滤波器的理论特性,选择压控电压源二阶滤波电路设计。通过TI的WEBENCH软件对巴特沃斯低通滤波器的设计进行了仿真,确定滤波器的运算放大器和外围元件参数。通过分析滤波器闭环频率响应曲线和阶跃响应曲线,验证了设计方案的正确性。研究表明,利用WEBENCH软件可以快速高效地完成滤波器的设计,该方法对实际滤波器的设计具有一定的参考价值。A design of the Butterworth low-pass filter is proposed based on WEBENCH software. The paper explores theoretical characteristics of Butterworth low-pass filter, and the design of the two-order filter circuit with voltage-controlled voltage source. The design of Butterworth low-pass filter has been simulated through TI WEBENCH software so that the operational amplifier and peripheral components parameter of the filter are determined. The validity of the design scheme is verified through the analysis of frequency response and step response of filter closed loop.Research shows that it can complete the filter design rapidly and effectively by using WEBENCH software,and it has some referential values for the design of the actual filter.
