采用电流传输器实现低通滤波器的精确补偿及仿真

Using current conveyer to realize the precise current - mode lowpass filter

以一个用第二代电流传输器（ＣＣＩＩ） 实现三阶低通滤波器的例子来分析电路工作在非理想状态下的精确补偿方式，并进行计算机仿真。

Based on the example of using the second - genera tion current conveyer (CCII) to realize the current- mode third - orderlowpassfilter ,this paper describes the precise compensation method ofthe circuit working in the unideal conditions.The computer simulation shows thatthe circuit has a low active -sensitivity .
