Objective

The main objective of this paper is to increase the noise immunity with tunable hysteresis by using sub-threshold differential CMOS Schmitt trigger. The circuit is designed in a 0.18nm standard CMOS process with a 0.6 V power supply which makes it a suitable candidate for low-power applications

Abstract

In this project, a sub-threshold differential CMOS Schmitt trigger with tunable hysteresis is proposed and it can be used to enhance the noise immunity of low-power electronic systems. By exploiting the body bias technique, Hysteresis of the proposed Schmitt trigger can be adjusted. This proposed circuit consumes less power consumption which makes it a suitable for low-power applications such as portable electronic, biomedical, and bio-implantable systems.

Keywords: Differential CMOS Schmitt trigger, body bias technique, Hysteresis.
