Abstract
A solid-state imaging device includes a source-follower amplifier having a driver transistor and a load circuit connected to the driver transistor. The load circuit is structured by a first MOS transistor having a gate with a fixed potential, and a load device connected to a source of the first MOS transistor. Furthermore, the load circuit of the source-follower amplifier is structured by a plurality of serially connected MOS transistors. Furthermore, by adapting a structure using a current mirror circuit, load conductance is reduced.
