摘要：This device for detecting an electromagnetic radiation, comprises a matrix ofjuxtaposed elementary sensors (), each associated with a common substrate in which a

sequential addressing read circuit is prepared, specific to each of the sensors, therebyconstituting as many pixels, the interaction of the radiation with the sensors generatingelectric charges to be converted to voltage for their subsequent processing, each of thesaid sensors being biased via an injection transistor (), of which one of the terminals isconnected to an integration capacitance (), storing the electric charges generated by thesensor during an integration phase, and whereof the quantity of charges is thenprocessed for conversion to voltage. Each of the pixels of the said matrix is associatedwith a current limiting device (), for limiting the current generated by each of theelementary sensors to a maximum called reference current, regardless of the radiationflux received by the pixel concerned.
