US 2002/0158974 A1 · X-Y address type solid-state image pickup device

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 photodiode 10, a reset transistor 12, a source follower amplifier 14, and a horizontal selection transistor 16 are formed in each of pixel regions Pmn. A kTC noise reduction circuit 6VR1 for reducing a kTC noise and a CDS circuit 6CL1 are formed outside of the pixel regions Pmn. A differential amplifier is constituted by a first differential transistor 62 of the kTC noise reduction circuit 6VR1 and the source follower amplifier 14 in each of the pixel regions Pmn.

Dependent claims

An X-Y address type solid-state image pickup device, comprising:

a pixel region including a photoelectric transducer for performing photoelectric conversion of incident light, a reset transistor for resetting the photoelectric transducer, an amplifying transistor for converting an electric charge stored in the photoelectric transducer into a voltage, and a horizontal selection transistor for outputting the voltage as image data to a vertical selection line on the basis of a horizontal selection signal outputted to a horizontal selection line;
and
a kTC noise reduction circuit for reducing a kTC noise generated at a time of the resetting.

Dependencies are inferred from the claim text.
