Voltage Mode First Order Filter Based on Current Controlled Current Conveyor Transconductance Amplifier

Abstract

A new voltage mode first order multifunction filter configuration using current controlled current conveyor transconductance amplifier is presented. In addition the proposed filter circuit employs one active element, three resistors and one grounded capacitor which makes it suitable for IC implementation. The circuit facilitates electronic control of the pole frequency with the help of bias current. Sensitivity study and the non idealities of the proposed circuit have been included. The circuit enjoys low sensitivity figures. The performances of the proposed circuit are verified using PSpice simulations with attractive results.
