In order to solve the problems of low-voltage and low-power comparator,the circuit technology of low voltage and feedback was investigated.The circuit structure and power consumption of the comparator were analyzed.The comparator can be used in low voltage by using only one regeneration latch.And only the dynamic power consumption was consumed.By the digital logic detection circuit,the comparator was detected and shutten down.When the comparison was over,the average power consumption of the comparator was reduced efficiently.At last,the low voltage comparator with feedback was simulated by Cadence.The simulation results show that the low voltage comparator with feedback is suit for low voltage with very low power consumption.
