Claim:
1. A photoelectric conversion device comprising: a photoelectric conversion unit; a differential amplifier configured to output a current signal based on an amount of charges generated by the photoelectric conversion unit, wherein the differential amplifier includes a first input transistor and a second input transistor forming a differential pair; a transfer transistor directly connected to a gate of the first input transistor, and configured to transfer a charge generated by the photoelectric conversion unit to the gate of the first input transistor; a reset voltage providing unit configured to provide a reset voltage for the gate of the first input transistor and a gate of the second input transistor; a reset transistor electrically connected to either one of the gate of the first input transistor or the gate of the second input transistor, and configured to control an electrical connection between the reset voltage providing unit and the gate connected to the reset transistor; and a connection transistor configured to control an electrical connection between the gate of the first input transistor and the gate of the second input transistor, wherein a source of the connection transistor is directly connected to the gate of the first input transistor, and a drain of the connection transistor is directly connected to the gate of the second input transistor.
