ABSTRACT:
The invention relates to an X-Y address type solid-state image pickup device manufactured by a CMOS process, and has an object to provide an X-Y address type solid-state image pickup device which has a small element size and a wide opening ratio, and can reduce a kTC noise. A photodiode10,a reset transistor12,a source follower amplifier14,and a horizontal selection transistor16are formed in each of pixel regions Pmn. A kTC noise reduction circuit6VR1for reducing a kTC noise and a CDS circuit6CL1are formed outside of the pixel regions Pmn. A differential amplifier is constituted by a first differential transistor62of the kTC noise reduction circuit6VR1and the source follower amplifier14in each of the pixel regions Pmn.
