Apparatus and a method for low noise sensing

Apparatus and a method for low noise sensing

The invention provides a method and apparatus. The apparatus includes a pixel ( 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 (...

description The invention provides a method and apparatus. The apparatus includes a pixel ( 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 ).
