Abstract
As a reset transistor is turned on, an FD (Floating Diffusion) is reset to VDD and then stores charges transferred from a light receiving element. By a source-follower circuit formed by an amplifying transistor, a selection transistor and a current source, a voltage in accordance with a potential of FD is output to a data line. A second output circuit generates an output voltage VOUT in accordance with the potential of FD at an output node. Output transistors in output circuit are configured to generate a potential difference equivalent to the potential difference between FD and data line caused by the amplifying transistor and selection transistor, between data line and output node.
