一系列基于CCⅡ的Q增强二阶滤波器

A series of CCⅡ-based enhanced Q second-order filters

本文提出了一种用单块有源CCⅡ实现的新型有源网络，它可以实现二阶高通、低通和带通滤波器，其特点是电路的ω0和Q值可分别由两个接地元件独立调节，文中还给出了电路的设计、灵敏度分析和实验结果。

By using a single current conveyor, a novel active network is proposed for realizing second - culer highpass, lowpass and bandpass filters. The advantage of these circuits is that the we and QOf the circuits are independently cotrolable through two grounded elements. The results of the circuitdesign and sensitivity analysis as well as experiment have also been given in this paper.
