A photoelectric conversion unit generates an amount of charges. A differential amplifier has first and second input transistors and is configured to output a current signal based on the amount of charges. A reset voltage providing unit is configured to provide a reset voltage for input nodes of the first and second input transistors. A transfer transistor is electrically connected to, and configured to transfer a charge to, the input node of the first input transistor. A reset transistor is electrically connected to one of the input nodes, and configured to control an electrical connection between the reset voltage providing unit and the input node connected to the reset transistor. A connection transistor has first and second nodes and is configured to control an electrical connection between the input nodes. The first and second nodes are connected to the input nodes of the first and second input transistors, respectively. |
