Abstract
The Analog to Digital converters play an imperative role in todays electronic systems world. Current applications need High Speed and Low Power ADC. Flash ADC is most prevalent not only for its highest transformation rate but also for its use in other ADC types and its varied applications. Traditional N-bit flash ADC necessitates 2N-1 comparator and same number of preamplifier. if we use multiplexer to design FLASH ADC number of Comparator and Preamplifier get reduced also use of mux in Thermometer to binary code encoder will reduce delay which will ultimately reduce overall power consumption ,area and will rise the speed of operation. https://journalnx.com/journal-article/20150447
