Abstract
A new pixel in semiconductor technology comprises a photo-sensitive detection region () for converting an electromagnetic wave field into an electric signal of flowing charges, a separated demodulation region () with at least two output nodes (D, D) and means (IG, DG, IG, DG) for sampling the charge-current signal at least two different time intervals within a modulation period. A contact node (K) links the detection region () to the demodulation region (). A drift field accomplishes the transfer of the electric signal of flowing charges from the detection region to the contact node. The electric signal of flowing charges is then transferred from the contact node (K) during each of the two time intervals to the two output nodes allocated to the respective time interval. The separation of the demodulation and the detection regions provides a pixel capable of demodulating electromagnetic wave field at high speed and with high sensitivity.
