通过典型实例，提出了开关电流滤波器的一种新颖的设计方法，该法遵循从 Ｒ Ｌ Ｃ滤波器到有源 Ｒ Ｃ滤波器，然后到开关电容滤波器，最后到不存在有限传输零点的开关电流滤波器的顺序进行设计，方法简单易行．由于 Ｒ Ｌ Ｃ滤波器的设计有表册可查，据此可以很方便地设计出具有各种性能指标的开关电流滤波器
By a typical example, a novel design method of switching current filter is proposed. The method follows from R L C filter to active R C filter and then to switched capacitor filter, finally to the absence of finite transmission zero Switching current filter in the order of design, the method is simple and easy. Because of the design of RLC filter can check the list, according to which can be easily designed with a variety of performance switching current filter
