摘要：A device for detecting electromagnetic radiations implements a detectioncircuit associated with a reading circuit. The detection circuit includes an array ofdetection pixels, each comprising a thermal detector of biased bolometric type, and

delivering an electric current signal representative of detected radiation. The signalundergoes a double baselining, respectively: a global baselining carried out by means ofa thermally isolated bolometer, ensuring extraction from the signal, of a first current ofconstant value inherent to the biasing of the thermal detector, and an adaptive baseliningspecific to each of the pixels, carried out by a programmable current generatorgenerating a current for subtraction from the current signal, as a function of the

dispersion inherent to the pixel considered relative to a reference signal and stored in anassociated memory integrated at the level of each of the pixels.
