Study and analysis of Low Power Dynamic Comparator for IOT Application

Abstract

The Internet of Things (IoT) applies the sensors and MCUs on various machines, devices and equipment, and connect them through internet. This brief presents the design of a low power dynamic comparator circuit which is compatible with wide range of applications (i.e., internet of things (IoT) sensors and integrated analog to digital convertor).In this paper different types of comparator-Conventional dynamic comparator, double tail dynamic comparator and dynamic comparator with enhanced latch regeneration speed have been analyzed. Dynamic comparator with enhanced latch regeneration speed is better than previous two conventional dynamic comparator in terms of power and speed.
