Abstract
A body-biasing compensation scheme based on two proportional-to-absolute-temperature (PTAT) circuits is proposed to reduce the PVT variability of the DC gain of cascode amplifiers. A brief description of a basic PTAT is given as well as its application to cascode-based operational transconductance amplifiers. Simulation results show that the proposed compensated circuit amplifier exhibit a (DC) gain variability smaller than the original (uncompensated) circuit, while reaching a gain enhancement of about 3 dB.
