Performance analysis of double tail dynamic comparators

Low power high speed and high precision comparator circuits are studied. Dynamic comparators are key building block for the implementation of analog to digital converters, sense amplifiers. High precision, low voltage operation, lower power consumption, high speed, less offset voltage and more reliability and are some of the important factors in designing the dynamic comparators. Since one circuit cannot provide all the mentioned properties, attempt is being made to study the performance of some dynamic comparators and compare their properties to ease the selection of suitable comparator circuit depending on the application. The circuits were rebuilt using GPDK (General Purpose Design Kit) 180nm CMOS technology in Cadence virtuoso tool.
