本文利用MAXIM公司的8阶低通开关电容滤波器MAX296设计了输出频率为0~10kHz的柔性波形发生器的滤波电路。文中分析了MAX296的工作特性,阐述了基于MAX296低通滤波器的设计方法,并且通过实验验证了该滤波电路可以满足该柔性波形发生器的滤波需求。
This paper presents a way to design the low pass filter circuit for 0-10kHz flexible waveform generator on an integrated active filter chip MAX296,which is produced by MAXIM. The paper analyzes the operating characteristic of MAX296 and states a way to design the low pass filter that is based on MAX296. At last, the experiment results illustrate that the low pass filter circuit design is suitable for the flexible waveform generator.
