摘要

A new dynamic comparator with or set elimination circuit is proposed. The offset elimination circuit decreases the influence of the or set voltage effectively and increases the resolution of the comparator. The simulation results show that, if the pre-set or set voltage is 10 mV, the or set elimination circuit can decrease to the enough low value, which meets the requirements of the system. The standard deviation of the offset voltage decreases from 7.27mV to 1.15mV with the utilization of the offset elimination circuit in Monte Carlo simulation.
