Voltage-mode multifunction filter with single input and three outputs based on single plus-type DVCC

A single input and three outputs voltage-mode multifunction biquadratic filter using a single plus-type differential voltage current conveyor, two capacitors and three resistors is presented. The proposed circuit offers the following features: realization of three filter functions, which are, lowpass, bandpass, and highpass filters, simultaneously, the use of only single plus-type differential voltage current conveyor, no need to employ inverting type input signals and no need to impose component choice. Experimental and H-Spice simulation results are also included.
