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 photodiodea reset transistora source follower amplifierand a horizontal selection transistorare formed in each of pixel regions Pmn. A kTC noise reduction circuitVRfor reducing a kTC noise and a CDS circuitCLare formed outside of the pixel regions Pmn. A differential amplifier is constituted by a first differential transistorof the kTC noise reduction circuitVRand the source follower amplifierin each of the pixel regions Pmn.
