Publication number: 20110168892Abstract: The present invention provides a radiation sensor featuring a plurality of individual sensor elements, e.g. pixels, each of which having a radiation detection portion that is adapted to generate an electric current in response to impingement of electromagnetic radiation and a current amplifier for amplifying the photoelectric current generated by the radiation detection portion. Current amplification is therefore performed locally within each pixel of the radiation sensor itself. This local current amplification effectively allows to increase sensitivity and response of the radiation sensor and therefore enables implementation of the radiation sensor on the basis of CMOS technology.Type: ApplicationFiled: December 19, 2005Publication date: July 14, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Roger Steadman, Gereon Vogtmeier, Ingo Hehemann, Salah Eddine Ibnou Quossai, Erol Oezkan, Armin Kemna
