Abstract

A circuit includes a photodiode electrically coupled to a first node, the first node configured to be charged by a first power supply voltage. A second node is configured to be charged by a second power supply voltage lower than the first power supply voltage, a source follower transistor is electrically coupled between the second node and a column line, and a level shifter is electrically coupled between the first node and the second node.
