Dual-outputs Current Controlled Differential Voltage Current Conveyor and Its Applications

Abstract

This article introduces a basic current-mode building block for analog signal processing, namely current controlled differencing voltage current conveyor (CCDVCC). Its parasitic resistance at input port can be controlled by input bias current. It is very suitable to use in analog signal processing circuits. The proposed element is realized in a CMOS technology and is examined the performances through PSPICE simulations. They display usability of the proposed active element, where the maximum bandwidth is 48.97 MHz. In addition, some applications as instrumentation amplifier, floating positive/negative resistance simulators and quadrature oscillator are included. They well confirm usefulness of the proposed element
