Claim Text:
1. A photoelectric conversion device comprising: a plurality of photoelectric conversion units; and a readout portion configured to output current signals to an output line, each of the current signals being based on an amount of charges generated by a corresponding one of the photoelectric conversion units; wherein the readout portion includes a plurality of transistors including at least a plurality of first input transistors and a plurality of second input transistors, each of the first input transistors and a corresponding one of the second input transistor forming a differential pair, wherein the plurality of transistors include a plurality of first selection transistors, each of the first selection transistors being electrically connected to a source of a corresponding one of the first input transistors and a source of a corresponding one of the second input transistors, wherein the plurality of the first selection transistors are repeatedly arranged correspondingly to every one or more of the photoelectric conversion units, wherein the plurality of transistors include a plurality of second selection transistors, each of the second selection transistors being electrically connected to a drain of a corresponding one of the second input transistors, wherein the plurality of the second selection transistors are repeatedly arranged correspondingly to every one or more of the photoelectric conversion units, and wherein, of the plurality of the transistors, any transistors repeatedly arranged correspondingly to every one or more of the photoelectric conversion units have the same conductivity type.
