Portable electronic devices have extremely low power requirement to maximize the battery lifetime. Various device circuit architectural level techniques have been implemented to minimize the power consumption. Supply voltage scaling has significant impact on the overall power dissipation. The Schmitt Trigger is a comparator circuit that incorporates positive feedback. Schmitt triggers are extensively used in digital as well as analog systems to filter out any noise present in a signal line and

The 45nm CMOS technology gives better results in terms of power and surface area as compare to 65nm and 90nm CMOS layout of Schmitt trigger. The design and simulation are performed of Schmitt triggers using DSCH and MICROWIND tools.
