Abstract

The photoelectric conversion device includes a plurality of pixels each including a photoelectric conversion unit and an amplification unit configured to amplifies a signal based on charge generated by the photoelectric conversion unit, an output line connected to the plurality of pixels, an interconnection disposed adjacent to the output line, and a current source circuit connected to the output line and configured to supply a current to the amplification unit of the pixel via the output line. The current source circuit includes a current source transistor connected between the interconnection and a fixed voltage node, and a cascode transistor connected between the interconnection and the output line.
