APPARATUS AND A METHOD FOR LOW NOISE SENSING

The invention provides a method and apparatus. The apparatus includes a pixels (10) adapted to receive light and to output a current representative of the received light; a feedback circuitry (20), connected to the pixel (10), adapted to receive said current and to receive a reference current (Iref) and to provide a feedback signal to the pixel (10) at least during at least a reset stage of the pixel (10). The method includes: (i) receiving light, by a pixel 10), and providing a pixel output signal representative of the received light; (ii) receiving, by a feedback circuitry, the pixel output signal; and (iii) providing multiple feedback signals to the pixel at least during a reset stage of the pixel (10).
