Abstract
A voltage-mode multifunctional biquadratic filter with three input terminals and single output terminal is presented. The proposed circuit is constructed using only one differential voltage current conveyor (DVCC) as active element and minimum number of passive elements, namely two resistors and two capacitors. The circuit can simultaneously realize all five different biquadratic filtering lowpass, bandpass, highpass, bandstop and allpass responses from the same configuration. The non-ideal effects of the presented filter are examined. PSPICE simulations of the proposed circuit are included using 0.35-μm CMOS technology from TSMC.
