提出了一种用第二代电流传送器 [CCII+]的接地仿真电感电路 ,并利用此CCII +仿真电感设计了一个基于 LC梯形的电流模式五价高通滤波器 ,此法可进一步推广到更高阶高通滤波器的设计 .文中对截止频率分别为 10kHz ,2 5kHz ,10 0kHz的电流模式五阶Butterworth滤波器进行了计算机仿真 ,模拟结果与理论分析一致
A new type of current-mode pentavalent high-pass filter based on LC trapezoid is proposed by using the second-generation current transmitter [CCII +] for ground emulation inductive circuit. This CCII + emulation inductor can be further extended to higher Order high-pass filter design.In this paper, the current mode fifth-order Butterworth filter whose cut-off frequency is 10kHz, 25kHz and 100kHz respectively is simulated by computer, and the simulation results are consistent with the theoretical analysis
