摘　　要：提出了以第二代电流传送器（ＣＣⅡ）作为有源器件，用信号流图（ＳＦＧ）法实现通用双二阶电流滤波器的方法，给出了设计实例。由于所实现的电路仅需要ＣＣⅡ器件和接地是阻、电容，因此易于全集成。A kind of current filter is introduced,in which the second generation of cur-rent conveyer(CCⅡ)is used as active component,and by means of signal flow graph(SFG) method to implement universal dual 2nd order current fil-ter.It not only reveals the inherent merits of CCⅡ but also eases the art of integrated due to its simplicity─merely CC Ⅱ,capacitors and grounded re-sistors.The design example is also shown.
