Abstract:
1. An array comprising a plurality of pixels being logically arranged in rows and columns, the pixels comprising a photoreceptor for converting impinging radiation into electronic charge, a transfer element for transferring the electronic charge towards a sense node, a reset transistor for resetting the sense node, means for converting the electronic charge onto the sense node into a voltage, and for outputting the voltage as a pixel signal, means adapted for biasing the sense nodes at a low voltage lower than a reset voltage which is meant to initialize the photoreceptor, during integration of impinging radiation on the photoreceptors, wherein the means for converting and outputting comprise a source follower for converting the electronic charge, and a select transistor for outputting the voltage as a pixel signal, the reset transistor of at least one pixel is coupled with one main electrode to the gate of the reset transistor of another pixel, and the reset transistor of said at least one pixel is furthermore coupled with another main electrode to the sense node of the at least one pixel.
