Design and Simulation of Third Generation Current Conveyor and Its Application

Abstract

This project report deals with the design of first generation current conveyor,second generation current conveyor and third generation current conveyor. Current controlled conveyor-II is also designed with trans linear structure. By using CCC-II,its X and Z node trans impedance will vary and it will be useful for filter application. By combining two second generation current conveyors(CCII+),we achieve third generation current conveyor. This allows to achieve very good results in the systems with a very low power supply. This design of third generation current conveyor is simulated using a standard 0.18um TSMC 1P,6M CMOS process in design architect and IC station from Mentor Graphics. Its DC,AC and Transient analysis is carried out with ELDO tool. Its pre layout and post layout results are compared which show 3.67% variation between functions. The versatility of this circuit will find applications in many areas. In this report,current sensing application is designed with CCIII. This application will use to find current flowing in to the signal. Therefore,it is very useful in low voltage low power current measuring devices. Furthermore, its applications as integrator and differentiator are designed and simulated.
