<![CDATA[Comparator is one of the main blocks that play a vital task in the performance of analog to digital converters (ADC) in all modern technology devices. High-speed devices with low voltage and low power are considered essential for industrial applications. The design of a low-power comparator with high speed is required to accomplish the requirements mostly in electronic devices that are necessary for high-speed ADCs. However, a high-speed device that leads the scaling down of CMOS process technology will consume more power. Thus, power reduction techniques such as multi-threshold super cut-off stack (MTSCStack), dual-threshold transistor stacking (DTTS), a bulk-driven, and a bulk-driven differential pair were studied in this work. This study aims to find and build the combination of these techniques to produce a comparator that can operate in low power without compromising existing performance using the 0.13-µm CMOS process. A comparator with a combination of MTSCStack, DTTS, and NMOS bulk-driven differential pair shows the most promising result of 6.29 µW for static power, 17.15 µW for dynamic power, and 23.44 µW for total power.]]>
