A new configuration for realizing high input impedance voltage-mode biquadratic filters with two inputs and one output is presented. The proposed configuration uses two second generation current conveyors (CCII's) of different polarity, two resistors, and two capacitors. The present configuration is capable of realizing band pass (BP), all pass (AP), and notch filter functions. The circuit demonstrates low active and passive sensitivity performance. The experimental results are found in good agreement with the theoretical predictions

Keywords: Active filters, band pass filter, all pass filter, notch filter, current conveyor.
