The Differential Voltage Current Controlled Conveyor Tranconductance Amplifier: A Novel Active Block Prevailing Op-Amp Limitations

Abstract

The differential difference current controlled current conveyor transconductance amplifier (DVCCCTA) is a novel active building block which can substitute the widely used operational amplifier in analog circuit design. The operation of differential difference current controlled current conveyor transconductance amplifier is different from the operation of operational amplifier. The DVCCCTA can be used to design various circuits like integrator, differentiator, adder, substractor etc. The advantages of DVCCCTA are it has high slew rate, wide bandwidth, and also current processing capabilities at input terminals. Since DVCCCTA is not slew limited in the same fashion of OPAMP, it can provide amplification of high frequency signals with a constant bandwidth virtually independent of gain.
