Patent ID: 7515185

Claim:
A solid-state imaging device having a pixel portion comprised of a plurality of unit pixels and a peripheral circuit portion for controlling the pixel portion, wherein the peripheral circuit portion operates with a first power supply voltage of a first power supply system and the pixel portion operates with a second power supply voltage of a second power supply system having a value different from that of the first power supply voltage, said solid-state imaging device comprising: a first power supply inputting portion for receiving as input the first power supply voltage of the first power supply system from the outside and a second power supply inputting portion for receiving as input the second power supply voltage from the outside and supplying the same to the pixel portion; a column area for storing signals of each pixel row adjoining said pixel portion; a level shifting unit for converting a level of said first power supply voltage and supplying a power supply voltage generated by said level shifting unit to a predetermined location; characterized in that: said unit pixel has at least a photo-electric conversion unit generating a signal charge in accordance with an amount of light received, a charge detection unit for acquiring a signal charge generated by said photoelectric conversion unit, a transferring unit for transferring a signal charge generated by said photoelectric conversion unit to said charge detection unit, a resetting unit for resetting said photo-electric conversion unit, and an amplifying unit for converting a signal charge of said charge detection unit to an electric signal and outputting it to an output signal line, and said level shifting unit supplies a level shifted power supply voltage to the transferring unit and resetting unit.
