A new second-order active universal filter with single input and three outputs using operational floating current conveyor

Abstract

A new active universal filter with single input and three outputs using Operational Floating Current Conveyor (OFCC) is presented. The configuration uses four OFCC, two grounded capacitors and three resistors. The proposed filter offers the following advantageous: (1) Using active elements of the same type (four OFCC). (2) Realization of low pass, band pass and high pass, filters simultaneously. (3) No requirements for component matching conditions or cancellation constraints, which makes the universal filter easier to design. (4) Orthogonal adjustment of /spl omega//sub 0/ and Q. (5) the circuit has low sensitivity to passive components, (6) using active elements of the same type (four OFCC) and (7) all the passive elements are grounded. The simulation results show that the proposed filter performs its functions properly.
