A Review of Frequency Compensation Technique In Multistage Operational Amplifier For Low Power &High Gain Applications

Abstract

Operational transconductance amplifiers (OTAs), are the rudimentary components for many analog systems, have received a loads of enthrallment in the literature due to their three-stage compensation. Over the recent years, a wide range of conclusions to the stability issue of such OTAs have been put forth, each with a idiosyncratic set of attributions or intended use. This study catechizes a wide range of anteriorly prevalent designs, insinuates a novel genus system that illuminates traits that unfold to be ubiquitous to various compensation structures, and enlighten which kind of OTA is best for a given application.
