Also Available Domains Transistor Logic|Tanner EDA|Cadence EDA

Project Code :TVMATO1012

Objective

The main objective of this paper is to design efficient Instrumentation Amplifier in terms of Area and power consumption. The designs of IA is built using Psuedo differential logic and also single ended topology.

Abstract

Abstract:

Inverter based Instrumentation Amplifier provides low power consumption and less area. In Conventional, the Inverter is based on Single Ended topology. The design of Instrumentational Amplifier based on SE topology offers high CMRR which is most disadvantage in this structure. In this paper, pseudo differential inverter is proposed. Using this structure, the Instrumentational Amplifier is designed. This novel structure of Instrumentational Amplifier is designed and simulated using Tanner EDA.
