Abstract
A photoelectric conversion apparatus includes a plurality of pixels each including a first avalanche photodiode and a second avalanche photodiode having a light-receiving surface area size different from a light-receiving surface area size of the first avalanche photodiode. The first avalanche photodiode is connected between a first waveform shaping circuit and a first switch. The second avalanche photodiode is connected between a second waveform shaping circuit and a second switch. An inverter circuit is connected between a control node of the first switch and a control node of the second switch.
