Article
Comparators are the key structure of any analog-to-digital-converters (ADCs). In recent days various low power and high-speed comparators have been introduced and reported by many researchers. This paper presents an examination of various kinds of comparators which is the second most generally utilized hardware block. The preamplifier stage is main...
Article
In low power electronics technology, a lot of new technology has already been introduced to reduce the power consumption of comparator. This paper presents the comparative study of preamplifier circuit on power consumption and delay prospects. The preamplifiers are explained to make the clear difference in the state-of the art. Every circuit has th...

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 de...
