采用单FTFN的电流模式全通陷波滤波器实现

Relization of Current mode All pass/Notch Filter Using Single FTFN

提出了采用单四端浮点零器（ＦＴＦＮ）实现电流模式二阶全通／陷波和一阶全通滤波器新电路．

A novel circuit configuration for realizing current mode second order allpass/notch and first order allpass filter using a single four terminal floating nullor(FTFN) is proposed. The circuit has the characteristics of highoutput impedance and low passive sensitivity.
