摘要
为了更有效地抑制偶次谐波及共模干扰信号,提出了基于MOCCⅡ的高阶差分式跳耦结构电流模式滤波器电路及设计方法．对提出的电路进行了截止频率为1MHz的四阶巴特沃斯滤波器的计算机PSPICE仿真．该电路对偶次谐波及共模干扰信号有较好的抑制作用,且保留了无源梯形网络灵敏度低的特点．
In order to restrain odd-order harmonic distortion and common model disturbing signal effectively, a MOCCⅡ -based filter circuit with high-order fully differential leapfrog-type current mode is presented and corresponding design scheme is proposed. The PSPICE simulation to 4th Butterworth filter with 1 MHz but frequency is made. Simulation results show that the circuit can restrain odd-order harmonic distortion and common model disturbing signal more effectively, with low sensitifity of passive LC ladder-type network.
