A compact high gain opamp for Bio-medical applications in 45nm CMOS technology

Abstract

In this paper a low opamp compensation technique suitable for the bio-medical application has been proposed and intuitive explained the existing compensation techniques. The Present technique relies on the passive damping factor control rather power hungry damping. Implemented in 45nm CMOS technology and simulated with Spectre. Simulation results shows that 100dB dc gain, well compensated 25MHz bandwidth opamp while driving a 1pF capacitive load. Draws with 12uW power consumption from 1V supply and occupying 0.004875mm2 silicon area.
