In today's era, where the demand for portable battery operated devices is rising, the researchers are focusing towards low power methodologies for high speed applications. One of major application is Analog-to-Digital Converters (ADCs), where the low power dissipation and high speed is ultimate target. The main component, which limits the performance of ADC, is the comparator. There are many types of comparators available according to requirement and type of ADC. Typical comparators are of differential type of architecture.
