Abstract
The present disclosure relates to a sensor having pixels, each pixel having photodiodes having each a terminal coupled to a first node associated with the photodiode; and an amplifier having a first part and, for each photodiode, a second part associated with the photodiode. The first part includes an output of the amplifier and a first MOS transistor of a differential pair. Each second part includes a second MOS transistor of the differential pair having its gate coupled to the first node associated with the photodiode the second part is associated with; a first switch coupling a source of the second transistor to the first part of the amplifier; and a second switch coupling a drain of the second transistor to the first part of the amplifier.
