  • Publication number: 20210067724
    Abstract: An AD conversion circuit includes a comparator configured to compare an analog signal with a ramp signal and output a comparison result signal indicating a result of the comparison, and performs an AD conversion using the comparison result signal. In the comparison, a potential of the ramp signal changes with a lapse of time from a first potential to a second potential. Before the comparison, the potential of the ramp signal changes at a first change rate and then changes at a second change rate smaller than the first change rate, the potential of the ramp signal changes from the first potential to a third potential between the first potential and the second potential, and the comparator is reset in a state where the third potential is input to the comparator.
