Abstract

This paper presents a new voltage-mode multifunction biquad filter with three-input single-output using simple operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed circuit can simultaneously realize voltage-mode lowpass, bandpass, highpass, bandstop and allpass filter responses at a high impedance input terminal. The natural frequency and the quality factor can also be tuned orthogonally and separately through adjusting the bias currents of OTAs. The performances of the proposed circuit are simulated with PSPICE simulations to confirm the presented theory.
