Journal on Communication Engineering and Systems 2277-5242 3 1 16 21 Double Tail Dynamic Comparator, Flash ADC, Schmitt Trigger, Delta Modulator, Hysteresis Comparator The main building block of any portable electronic equipment is the Analog-to-Digital Converter. The increased demand of the portable electronic equipments has forced the circuit designers to use lower supply voltages. However, the performance of analog circuits is degraded at low supply voltage due to large power dissipation and higher noise occurrence. This makes the design of voltage analogue circuits more challenging. As comparator is the basic device of analog to digital converters, this paper aims to analyze the comparator design with hysteresis. This proposed technique reduces the power dissipation and noise. The results were compared with the double tail comparator, which operates with supply voltage of 0.6v. November 2013 - January 2014 Copyright © 2014 i-manager publications.
