Design of Active Filter using CMOS based IInd Generation Current Conveyor in Current Mode

Abstract

Traditional design techniques used in VLSI are in voltage mode, but these have drawbacks like low bandwidth, non-linearity and less gain. Current conveyors act similar to operational amplifiers but are advantageous over older VLSI design techniques because of high bandwidth-gain product, reduced power consumption etc. This paper consists of two parts: circuit diagram of current conveyor (which is a three terminal analog device) is discussed first and its working is analyzed, followed by the discussion on design of a universal active filter using current conveyor. If various bias currents are varied in active filter design across the passive components, the expected low-pass, high-pass and band-pass responses are obtained. This experiment was done in 45 nm CMOS technology using Cadence Virtuoso.
