Abstract
The present invention relates to a CMOS (Complementary Metal Oxide Semiconductor) image sensor; and, more particularly, to a pixel array of the CMOS image sensor in a wider dynamic range. A CMOS image sensor based on a correlated double sampling comprises a single common node, a plurality of unit pixels in parallel connected to the single common node, an amplifying means coupled to the single common node for amplifying a voltage of the single common node and outputting the amplified voltage, and an output means for receiving the amplified voltage from the amplifying means and outputting a data voltage level and a reset voltage level.
