Abstract

We show how the MOST threshold voltage can be reduced simply by forcing a constant current through the transistor bulk terminal. We characterize two versions of the resulting current driven bulk device by simulations, and conclude that this is a good method for improving circuit performance when the voltage supply is very low. Finally we show how the technique can be used to implement a 1 V folded cascode OTA with compatible input and output voltage ranges.
