用零极子对偶变换法实现电流模式电路

Use of nuller duality to realize current-mode circuit

基于对偶原理并借助零极子有源器件模型的对偶变换方法,实现电压模式电路到电流模式电路的转换,并给出四阶高通滤波器变换实例和PSPICE仿真结果。

A conversion method from voltage-mode circuit to current-mode circuit is described, the conversion of which is based on duality principle and transformation of nullor models of active devices. A conversion example of a four-order high-pass filter is given and PSPICE simulation results are reported.
