Abstract

A self-test circuit and a self-test method for a comparator are provided. A first output terminal of the comparator is coupled to an input terminal of a first inverter, and a second output terminal of the comparator is coupled to an input terminal of a second inverter. The comparator operates in a reset phase or a comparison phase according to a clock. The self-test method includes steps of: coupling the first output terminal and the second output terminal so that the comparator enters a test mode; and in the test mode, controlling the comparator to operate in the reset phase or the comparison phase according to the clock. In the test mode, the first output terminal and the second output terminal have substantially the same voltage.
