摘　　要：提出了一个新颖的基于同相第二代电流传输器（ＣＣⅡ＋）的电压模式滤波器的形式电路，根据该形式电路可以产生低通、带通、高通二阶滤波器。所有滤波器的无源ＲＣ元件全部接地，便于集成，且具有很低的无源灵敏度，极点增益及角频率、品质因数均可调节。A novel formal circuit of voltage mode filter is presented in the paper, which is bsed on the plus type of second generation current conveyor Lowpass, bandpass and highpass voltage mode second order filters can be obtained from this formal circuit With all passive RC elements grounded, the filter is easy to be integrated The circuit has very low passive sensitivity and its pole gain, corner frequency and quality factor are adjustable
