Abstract

Circuits (Fig. 1) that operate with power supplies (VDD) of less than 1 Volt are present. More particularly, circuits (Fig. 1) that operate with supply voltages (VDD) near or lower than the threshold voltage of the transistors (M1A, M1B) in those circuits are presented. Various circuits and embodiments such as operational transconductance amplifiers, biasing circuits, integrators, continuous-time sigma delta modulators, track-and-hold circuits, and others are presented. The techniques and circuits can be used in a wide range of applications and various transistors from metal-oxide-semiconductor (MOS) to bipolar junction transistors may implement the techniques presented herein.
