Abstract

A new high input impedance voltage-mode universal biquadratic filter with one input terminals and five output terminals is presented. The proposed circuit uses three plus-type differential difference current conveyors, two resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions: lowpass, bandpass, highpass, notch and allpass, simultaneously, without component matching conditions. The proposed circuit offers the features of high input impedance and the use of only grounded capacitors.
