CMOS Customization of Comparator

Abstract: In this paper, we present the customization methodology of high speed Flash ADC by optimizing its various components through CMOS channel length i.e comparator, so that the overall performance of the resulting Flash ADC or CMOS made device(s) is improved over traditional Flash ADC’s. Together with high speed as a parameter, components are designed so that they operate with sampling frequency as high as 70-75 MHz with lowest power consumption and operate on power supply voltage down to 2V for compatible with low power digital portion of the design as well as occupy less chip area. All the components are designed using the 90 nm CMOS technology.
