Design of Folded Cascode OTA in Different Regions by vathsala s is a document available to read on EtoBox.
This paper presents an optimized design methodology for a folded cascode operational transconductance amplifier (OTA) using the gm/ID approach, targeting applications in Sigma Delta analog-to-digital converters. The OTA is analyzed across three operational regions: weak, moderate, and strong inversion, achieving varying performance metrics such as DC gains of 75.5dB to 92dB and unity-gain frequencies from 19.14MHz to 430MHz. The study emphasizes the importance of transistor sizing and biasing in optimizing
