Design and Simulation of Operational Transconductance Amplifier Using Wilson Current Mirror

Prerna Nijhara, Pratibha Singh, Pradyumna Gaur

Abstract

This paper presents the design of Operational Transconductance Amplifier using Wilson Current Mirror with enhanced performance in comparison to the OTA using simple current mirror. Wilson Current Mirror is the modified form of the Simple Current Mirror. It has improved and better characteristics as compared to the earlier one and hence enhances the performance of the circuit in which it is used. Circuit is simulated and designed using Cadence Virtuoso at 180 nm technology nodes.
