Abstract
A photoelectric conversion device includes a pixel, a signal line connected to the pixel, and a first signal holding unit to which a signal is input from the pixel via the signal line. The first signal holding unit includes a first capacitor element and a second capacitor element each configured to hold a signal input from the signal line to a first terminal, an amplifier circuit in which a second terminal of the first capacitor element and a second terminal of the second capacitor element is connected to an input terminal, a first switch connected between the first terminal of the first capacitor element and an output terminal of the amplifier circuit, a second switch connected between the first terminal of the second capacitor element and the output terminal of the amplifier circuit, and a third switch connected to the input terminal of the amplifier circuit.
