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.
