Simulated Analysing of Fully Integrated MOS FET-C Sixth-order Low Pass Filter Based on the CF

本文提出了以电流跟随器ＣＦ为基本电路元件的全集成ＭＯＳＦＥＴ—Ｃ精确连续时间六阶低通滤波器电路，并应用ＰＳＰＩＣＥ—Ⅱ通用模拟电路程序，对其幅频特性和相频特性进行了计算机仿真分析，得出了实用的结论。

The paper gives the realization of fully integrated M OSFET -C precision continuous -time sixth -order low pass filter based on current follower [CF]. Using PSPICE -Ⅱ, Simulation and analySis of the characteristics of the output voltage amplitude-frequency response and phase -frequency response of a sixth order low pass filter have been done, practical conclusions are obtained.
