CMOS image sensor with NMOS-only global shutter and enhanced responsivity.

CMOS image sensor with NMOS-only global shutter and enhanced responsivity.

Most CMOS image sensors today use the rolling shutter approach to control the integration time. This pixel architecture is advantageous where minimal pixel size is required to increase resolution or reduce over all chip size. For imaging of a fast moving object or when used with pulsed illumination,...
