Abstract
A solid-state imaging device includes: a plurality of pixel circuits arranged in rows and columns; a plurality of unit power supply circuits that generate a second power supply voltage from a first power supply voltage based on a reference voltage and supply the second power supply voltage to amplifier transistors provided in the plurality of pixel circuits; and a regulator circuit that generates the reference voltage that is constant. Each of the unit power supply circuits is provided for a corresponding one of the columns of the plurality of pixel circuits or for a corresponding one of the pixel circuits, and supplies the second power supply voltage to the amplifier transistors in the pixel circuits that belong to the corresponding one of the columns or to the amplifier transistor in the corresponding one of the pixel circuits.
