n-th Order Current Mode Filter Design with Multiple Inputs and Single Output Based on MCCCII
-
摘要: 该文提出了一种结构简单的基于MCCCII的n阶多输入单输出电流模式滤波器电路。该滤波器电路包含n个有源器件、n个接地电容元件，无需接任何电阻元件，可以产生n阶低通、带通、高通、带阻及全通电流模式滤波。由于仅依靠改变外部输入电流信号的接入数目和方式来实现不同功能的滤波器，而电路内部结构及器件数目不变，所以该电路便于单片集成。文中对滤波器进行了PSPICE模拟。

Abstract: The paper presents the n-th order current mode filter circuit with multiple inputs and one output based on MCCCII (second generation Current Controlled Conveyor with Multiple outputs). The filter circuit which contains n active elements and n capacitors can produce nth order low-pass, band-pass, high-pass, band-stop filters. Various kinds of filters can be realized just by changing the amount and mode of joining external current signals to the circuit. Internal structure of circuit and amount of elements need not change. So the circuit is convenient to integrated .The paper also makes PSPICE simulation for the filter. -
