Abstract
A ramp signal output circuit includes a first reference current source transistor to which a current is supplied from a current source, a first line connecting a gate of the first reference current source transistor and a gate of a first current source transistor, a branch point where a second line branches from the first line, a first ramp signal generation unit connected to the first current source transistor, and a second ramp signal generation unit connected to a second current source transistor, wherein the second line is connected to a gate of the second current source transistor.
