Versatile Voltage-Mode Universal Filter Using Differential Difference Current Conveyor

Sudhanshu Maheshwari, Ankita Gangwar

Abstract

A novel four-input three-output voltage-mode differential difference current conveyor (DDCC) based universal filter is presented. The circuit uses three DDCCs as active elements, two resistors and two capacitors as passive elements. The circuit along with its versatility enjoys the advantage of minimum number of passive elements employment. SPICE simulation results are given to confirm the theoretical analysis. The proposed circuit is a novel addition to the existing knowledge on the subject.
