Unity Gain and Variable Gain OTA Buffer Amplifier with Resistive Load Using Multi-Gate Transistors

Abstract

Remya Jayachandran and Rama S Komaragiri

Analog buffer amplifier using reconfigurable FET and gate-all around FET devices are demonstrated to analyze the feasibility of using multi-gate device in analog circuits. In this paper, a unity gain OTA buffer and a simple configuration for a variable gain OTA buffer amplifier are presented. The gain can be varied without changing any other circuit parameters, thus making the configuration more flexible compared to the existing buffer amplifier designs.
