A REVIEW ON OPERATIONAL TRANSCONDUCTANCE AMPLIFIER (OTA) USING 180NM TECHNOLOGY Review Paper of OTA

Abstract

A mixed Signal IC can be a combination of Analog circuits and Embedded Software. This paper presents
design concept and review of Operational Transconductance Amplifier (OTA) using different types of OTA such as a (i)
Single Stage OTA (ii) Two stage OTA (iii) Folded Cascode OTA (iv) Telescopic OTA. Here also described two types of
techniques such as a (i) bulk driven technique and (ii) Gain boosting technique. Using different types and techniques and
types to measure different parameter such as Gain, Gain Margin, Phase Margin CMRR, Power Consumption etc. And
the simulated output measured by using 0.18µm or 180nm technology.
