摘　　要：讨论了应用一各种结构简单、性能优良的改进型电流传送器(MCCII) 的CMOS实现电路,构成电流模式跳耦滤波器的电路及其设计方法。电路中的有源元件数目少,所有的电容、电阻都接地, 适于实现全集成电流模式连续时间滤波器, 并且面向设计电路完成MOS管级的PSPICE(集成电路的模拟程序) 仿真, 结果表明所设计的电路方案正确。A current mode high pass filter based on a differential circuit having simple and leap frog structure with excellent performance is proposed. The filter has several advantages such as low sensitivity, lower power supply, higher frequency,etc. PSPICE simulation at MOS transistor level is carried out and the simulation results show that the proposed circuit is feasible.
