摘　　要：本文提出了以运算放大器为基础的一种新型电流模式MOSFET－C全集成精确连续时间平衡结构六阶低通滤波器电路。并应用PSPICE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，得出了几点实用的结论。This paper presents a new fully integrated MOSFET-C current mode sixth-order low-pass filter with precise continuous time balanced structure. Amplitude-frequency and phase-frequency characteristics of this filter have been derived by means of computer simulation using general purpose program PSPICE. The main points of conclusion can be put into practical use.
