Current controlled conveyor based transadmittance mode universal filter

Abstract

This paper presents a transadmittance mode universal filter with two inputs and four outputs using three multiple output current controlled conveyors (MO-CCCII) and two grounded capacitors. It can realize low pass, high pass, band pass, notch and all pass responses at high output impedance. The filter enjoys low sensitivity performance and low component spread; and exhibits electronic and orthogonal tunability of filter parameters via bias currents of MO-CCCII. SPICE simulation results confirm the workability of the proposed structure.
