Patent ID: 8199235

Claim:
An image sensing device comprising: a pixel array in which a plurality of pixels are arrayed; and a plurality of column amplification units that amplify a plurality of signals that are output in parallel from the pixel array, wherein each of the plurality of column amplification units includes: a differential amplifier including an amplification unit and a current source circuit, the amplification unit amplifying a signal that is output from the pixels and outputting the amplified signal to an output node, the current source circuit being arranged between the amplification unit and a first potential line and supplying a current to the amplification unit; a clip unit that clips a voltage of the output node when the differential amplifier amplifies the signal and thereby clipping a voltage of a node between the amplification unit and the current source circuit; and a second potential line commonly connected to the current source circuits of the plurality of column amplification units to control the current to each of the plurality of amplification units.
