Abstract
Low power consumption, high performance dynamic comparators are widely used in high-speed Analog to Digital Converters (ADCs) and advanced input/output circuits. Mostly unique comparators utilize the latching stage thorough cross-coupled inverters, which gives a solid positive feedback, to fasten the comparison and reduce the static- power dissipation. In this paper, the analysis of dynamic comparators having best performance parameters in terms of power dissipation is presented. This is achieved by adopting low power techniques like adding transistors and sizing them to get efficient circuit. The proposed circuits are able to reduce power dissipation from 40-50%.
