Abstract :
This paper presents a new voltage-mode multifunction filter with four inputs and three outputs employing three current controlled differential difference current conveyors (CCDDCCs) and two grounded capacitors. The proposed circuit can provide low-pass, band-pass, high-pass, band-stop and all-pass voltage responses by appropriately connecting the input and output terminals, at a high impedance input terminal which enable easy cascadability. The circuit parameters ω0 and Q can be set orthogonally by adjusting the circuit components. PSPICE simulation results are also performed to confirm the theoretical analysis.
