two-stage comparator, dynamic-bias comparator, FIA comparator.Abstract
This article mainly presents a summary of development of dynamic comparators and the optimization to conventional comparator in recent years. By comparing the design of two different comparators, the design method of less power consumption, high speed or small delay, and low input referred noise can be concluded. The Dynamic comparator is designed to have small delay and less power consumption compared with two-stage comparator. The dynamic-bias comparator spends less power for operation the circuit compared with double-tail comparator. The FIA comparator operates under the controlling of logic NOR gate.
