摘要
提出了一个新的基于ＣＣⅡ＋ 的电流模式二阶通用滤波电路，它可以分别实现二阶低通、高通、带通滤波功能．三种滤波器的极点角频率和品质因素均可调节，所有ＲＣ元件全部接地，便于集成。
This paper introduces a new current mode second order universal filtering circuit based on CCⅡ+.This circuit can realize second order lowpass,highpass,bandpass filtering function respectively.The pole angular frequency and quality factor of three kinds of filters can be adjusted.All of RC elements are grounded and every kind of filtering circuit has very low passive and active sensitivities.
