1. A photoelectric conversion apparatus comprising:
a plurality of pixels each including a photoelectric conversion unit configured to generate a charge based on an incident light and an amplification transistor having a control node configured to receive the charge and to serve as a first input node of a differential pair; and a plurality of transistors having respective control nodes configured to receive a common potential, wherein an operation of setting the control nodes of the plurality of transistors as a second input node of the differential pair while the plurality of transistors are in ON states and an operation of setting the control node of one of the plurality of transistors as a second input node while only one of the plurality of transistors is in an ON state are switched from one to another.
