Abstract
A comparator circuit with low power consumption and low kickback noise includes a first dynamic comparator and a second dynamic comparator. The first dynamic comparator is a pre-amplifier for the second dynamic comparator. An enable switch which is connected to the first dynamic comparator has a control terminal connected to a resistance device. The resistance device and the enable switch form a RC delay circuit to reduce the kickback noise of the comparator circuit. Since the comparator circuit is composed of dynamic comparators, the power consumption of the comparator circuit is lower.
