A pixel (10) for detecting radiation comprises a photoreceptor (11) for converting impinging radiation into electronic charge and for integrating the electronic charge, a transfer element (12) for transferring the electronic charge towards a sense node (16) where the electronic charge is converted into a voltage, a source follower (14) for temporarily buffering the voltage, and a select transistor (15) for outputting the voltage as a pixel signal. The pixel (10) further comprises first biasing means adapted for biasing the sense node (16) at a low voltage between about 0.25 V and about 1.0 V during integration of impinging radiation on the photoreceptor (11). |
