Analog-to-digital conversion is a process in which analog signal is changed into digital signal without changing its contents. A low power, low delay and a high speed analog to digital convertor uses clocked regenerative comparators for the reduction in delay and power. In this paper, transient analysis on the delay of clocked regenerative comparators is presented. Technology used for the simulation process is 180nm which shows reduced delay time up to 30% in conventional double-tail comparator i.e. 2.9088e-009 sec. at 0.8V.
