Abstract
A photosensitive sensor is capable of operating in a global shutter mode and in a rolling shutter mode. The sensor includes at least one pixel with a photosensitive region configured to photogenerate charges. A first transfer gate is configured to transfer photogenerated charges from the photosensitive region to a transfer node. A source-follower transistor is configured to transmit a reading signal to a read node, in the global shutter mode, in a manner controlled by a potential of the photogenerated charges on the transfer node. A second transfer gate is configured to transfer the photogenerated charges from the photosensitive region to the read node in the rolling shutter mode.
