CMOS dynamic comparators contributes a major role on the implementation of mixed signal successive approximation register (SAR) type of analog to digital converters (ADC). High precision, dynamic range, low voltage operation, high speed, low power consumption, reliability and offset voltage are the critical factors to be considered while designing CMOS dynamic comparators. This paper reviewed the performance of some popular dynamic CMOS comparators such as StrongARM latch comparator, double- tail dynamic-latched comparator, dynamic bias comparator and triple stage somparator.
