摘要： This device for detecting an electromagnetic radiation, comprises a matrix of juxtaposed elementary sensors (1), each associated with a common substrate in which a sequential addressing read circuit is prepared, specific to each of the sensors, thereby constituting as many pixels, the interaction of the radiation with the sensors generating electric charges to be converted to voltage for their subsequent processing, each of the said sensors being biased via an injection transistor (2), of which one of the terminals is connected to an integration capacitance (3), storing the electric charges generated by the sensor during an integration phase, and whereof the quantity of charges is then processed for conversion to voltage. Each of the pixels of the said matrix is associated with a current limiting device (5), for limiting the current generated by each of the elementary sensors to a maximum called reference current, regardless of the radiation flux received by the pixel concerned.
