Abstract
A photoelectric conversion apparatus includes a photoelectric conversion unit, a signal line, a circuit block, and a control circuit. The circuit block includes a differential amplifier circuit including a feedback path, a first switch that controls conduction between an output terminal and the signal line, a second switch that controls conduction between an inverting input terminal and the signal line, and a third switch that controls conduction between the inverting input terminal and the output terminal. The control circuit controls a signal for controlling the first switch and a signal for controlling the third switch to have the relation of logical NOT.
