摘　　要：提出了一种新的开关电流高阶椭圆低通滤波器通用综合方法,该法遵循从RLC滤波器到有源RC滤波器,再到开关电容滤波器,最后到开关电流滤波器的顺序进行设计,方法简单易行。文中给出了5阶开关电流椭圆低通滤波器的设计实例,ASIZ仿真频率响应满足所需的频率技术要求。A novel general synthesis method for switched -current （SI） high order elliptic low -pass filter circuit is presented. The designing procedure is from RLC prototype filter, active RC filter, and switched capacitor filter to switched current filter. A 5^th order switched current elliptic low - pass filter is designed in this paper. ASIZ simulation results for frequency response verify the technical requirement .
