Abstract
A solid state imaging device includes a plurality of pixels arranged in a matrix, a plurality of vertical signal lines VL arranged to correspond to columns of the pixels, respectively, such that each of them is connected to the pixels in each column and a column amplifier including a plurality of amplifiers AP. Each of the amplifiers AP includes a current source MOS transistor T, an amplifying MOS transistor Tfor amplifying an image signal and a cascode MOS transistor Twhich is cascode-connected to the amplifying MOS transistor and outputs an amplified image signal between the cascode MOS transistor Tand the current source MOS transistor T. Gate terminals of the cascode MOS transistors Tof the amplifiers AP are connected to each other.
