摘要
本文对第一代电流传输器和第二代电流传输器的实现原理以基本实现电路进行了详细的对比研究。介绍了一种二阶带通滤波器设计方法,只使用4个无源元件和两个电流传输器,不仅无源和有源灵敏度都很低,而且当无源参数确定后,有源参数对极点频率不产生影响,保持恒定。HSPICE仿真结果证实了理论分析的正确性,所提出的电路是可行的。
Two configurations for second order bandpass filters with current transfers are introduced.The circuits, which exhibit reduced values for the active and passive insensitivities.only use four passive components and necessitate two current conveyors. When the passive parameters determined, there is no impact of active parameters on the pole frequency w0, the w0 maintain a constant.HSPlCE simulated results,which confirm the theoretical analysis,are given and discussed for current conveyors imvlemented in a translinear form.
