Voltage Conveyor based Electronically Tunable Multifunction Biquadractic Filter

In this work, a new voltage-mode (VM) single-input single-output (SISO) multifunction biquadratic filter based on voltage conveyor (VC) is proposed. The proposition makes use of two voltage conveyors and six admittances. The proposed structure provides low-pass (LP), band-pass (BP) and high-pass (HP) responses simultaneously with appropriate selection of admittances. The performance of the proposed structure is verified through Spice simulations using AD844. The simulation results are found at par with the proposed theory. The proposed topology is electronically tunable.
