Abstract
A comparator testing circuit and a testing method are provided. The comparator testing circuit includes a switching circuit, a comparator, and a determination circuit. The switching circuit receives a first signal, a second signal, and a switching signal, and outputs one of the first signal and the second signal as a first input signal and the other of the first signal and the second signal as a second input signal according to the switching signal. The comparator compares the first input signal with the second input signal to generate an output signal. The determination circuit determines whether the comparator is abnormal based on the switching signal and the output signal to generate an exception flag.
