High‐speed low‐power common‐mode insensitive dynamic comparator

Abstract

A new structure single‐stage dynamic comparator with a large input common‐mode range is proposed. The proposed comparator is compared with previous dynamic comparators. With same size input transistors and load capacitance, it is more than 1.2 times faster with <80% power consumption. Also, the input‐referred noise and offset are no more than the previous comparators.
