Abstract

A high input and low output impedances voltage-mode universal biquadratic filter with three input terminals and one output terminal is presented. The proposed circuit uses one differential difference current conveyor (DDCC), two differential voltage current conveyors (DVCCs), one second-generation current conveyor (CCII), three grounded resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions, i.e. lowpass, bandpass, highpass, notch, and allpass from the same configuration. The proposed circuit offers the features of high input impedances, low output impedance, using only grounded resistors and capacitors, orthogonal controllability of resonance angular frequency and quality factor. It does not need passive components matching conditions.
