The new multifin approach for mitigation of leakage in an Operational Transconductance Amplifier

Abstract

In this paper presents the design and analysis of Conventional Operational Transconductance Amplifier for use in novel FinFET based OTA. OTA is an analog circuit and it has differential input voltage controlled current source (VCCS). OTA is a basic building block in analog circuit. In this, paper we focus on different-different supply voltage to find such type parameter like leakage power, integrated noise, leakage current, power consumption. The proposed design using FinFET has enhanced the performance parameter of the conventional OTA design. By using, novel FinFET OTA we reduce power consumption 1.024mW.The proposed OTA (implemented with FINFET) had fixed bias voltage at 0.7μA and supply voltage is 0.7V. The design and simulation of FINFET based OTA is done by using 45nm technology at cadence virtuoso version 6.1 platforms.
