MOSFET-C电流模式四阶带通滤波器的CCⅡ±实现及分析

Simulated Analysing of the Current' Version MOSFET--C Fourth-order Band Pass Filter Based on CC Ⅱ±

本文提出了以电流传输器CCⅡ±为基本电路元件的电流模式全集成MOSFET－C精确连续时间四阶带通滤波器电路，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 integratedcurrent version MOSFET-C precision continuous-timefourth-order band pass filter based on current conveyors CC Ⅱ±. Using PSPICE- Ⅱ, simulation and analysis of the characteristics of the output voltage amplitude-frequency response and phase-frequency responseof a fourth--order band pass filter have been done.Practical conclusions are obtained.
