A New DVCC+ Based Second-Order Current-Mode Universal Filter Consisting of only Grounded Capacitors

Abstract

In this paper, a new second-order current-mode universal filter using only two plus-Type differential voltage current conveyors, three resistors and two grounded capacitors is proposed. The proposed circuit with two identical inputs and three outputs can simultaneously provide second-order high output impedance low-pass, band-pass and notch filter responses. Also, it can realize high-pass and all-pass filter responses with interconnection of relevant output currents. It can be easily tuned electronically. It can be operated properly at high frequencies. A number of simulations based on SPICE program and an experimental test are achieved in order to demonstrate the performance of the proposed filter. © 2017 World Scientific Publishing Company.
