摘要
采用第二代电流传输器ＣＣⅡ为有源元件，应用信号流图的方法设计出一类通用电流模式滤波器，其所有Ｒ、Ｃ均接地，ω０、Ｑ和电流增益Ｋ均独立可调，敏感度低。
All kinds of universal current mode filters are implemented with SFG approach, using CCⅡ as active component. All R and C are grounded. ω 0、Q and K (current gain) can be adjusted independently. The sensitivity is low. Also, this method can be expanded for implementation of high order filter.
