Patent ID: 7129985

Claim:
A sensor integrated on a single semiconductor substrate, comprising: a sensor block including a pixel unit and a scanning unit for selecting a pixel of the pixel unit, the pixel unit comprising a plurality of pixels each including a light-receiving element, a floating diffusion region, a transfer MOS transistor for transferring an electric carrier in the light-receiving element to the floating diffusion region, an amplifying MOS transistor having a gate connected to the floating diffusion region, and a reset MOS transistor for resetting the electric carrier in the floating diffusion region; a signal processing block for processing a signal output from said sensor block; a single electric power voltage input terminal for externally inputting an electric power voltage from outside of the substrate; a first level shift means disposed on the substrate for level shifting a voltage supplied from the single electric power voltage input terminal to generate a first voltage, and for supplying the first voltage to a gate of the reset MOS transistor, wherein the first voltage is larger than a voltage supplied to a drain of the amplifying MOS transistor of the pixel; and a second level shift means disposed on the substrate for level shifting a voltage supplied from the single electric power voltage input terminal to generate a second voltage, and for supplying a second voltage to the signal processing block, wherein the second voltage is smaller in amplitude than the first voltage.
