Patent ID: 7791660

Claim:
A solid-state image sensing device comprising: a pixel array in which pixels are arranged in rows and columns, each of the pixels converting light to an image signal; vertical signal lines each of which runs on the pixel array in a column direction and is provided for each column for transferring the image signal in a form of a voltage signal, the image signal being read out of the pixel; a column amplification section including amplifiers each of which is provided for each column and amplifies the image signal transferred via the vertical signal line, the column amplification section being supplied with a power supply voltage and a ground voltage; a power supply line for supplying the power supply voltage to the amplifiers; and a ground line for supplying the ground voltage to the amplifiers, wherein with respect to each of the amplifiers, an impedance on a power supply side is greater than an impedance on a ground side, and said each amplifier includes: an amplification transistor whose source is connected to the ground line and whose gate electrode receives the image signal; and a transistor which is provided between the drain of the amplification transistor and the power supply line and which is continuously operated in the ON state, and said each amplifier outputs the amplified image signal from between the amplification transistor and the transistor.
