PROBLEM TO BE SOLVED: To provide a solid-state CMOS image sensor, specifically a CMOS image sensor pixel which has only two row lines per pixel, pinned photodiode for sensing light, and one or two column lines, and to provide its array. SOLUTION: The pixel does not have an address transistor and the sensing and reset transistors are both MOS p-channel type. This architecture results in a low noise operation with a very small noise operation. In addition, this new pixel architecture allows for the standard CDS signal processing operation, which reduces pixel to pixel non-uniformities and minimizes kTC reset noise. The pixel has high sensitivity, high conversion gain, high response uniformity, and low noise, which is enabled by the efficient 3T pixel layout. COPYRIGHT: (C)2008,JPO&INPIT
