Voltage-mode multifunction filter with single input and three outputs using two compound current conveyors

A voltage-mode low-pass, band-pass, and high-pass filter with single Input and three outputs, employing only two compound current conveyors, two grounded capacitors, and three resistors, is proposed. The proposed circuit offers the following advantageous features: realization of voltage-mode low-pass, band-pass, and high-pass filter responses from the same configuration; no requirement of critical component matching conditions; employment of grounded capacitors ideal for integration; low sensitivity characteristics; and simpler configuration due to the use of only two compound current conveyors.
