Abstract: An electronic circuit, for biasing and reading at least one resistive thermal detector, comprising: biasing means able to bias the resistive thermal detector by making a biasing current of substantially constant value flow in the resistive thermal detector when the electrical resistance thereof varies; conversion means able to convert a voltage at the terminals of the resistive thermal detector into a current, comprising at least one MOS-type transistor the gate of which is electrically connected to one of the terminals of the resistive thermal detector; means of generating a base clipping voltage electrically connected to the source of the MOS-type transistor of the conversion means.

Abstract: A device for detecting electromagnetic radiation, including pixels each detecting a radiation and providing an electric current representative of the detected radiation, a column to which the pixels are connected, and transmitting the electric currents provided by the pixels, and an electrical module, to which the transmission column is connected, processing the electric currents provided by the pixels. Each pixel includes a detection circuit including a bolometric detector connected in series to a voltage polarization device of the bolometric detector for adjusting the electric current supplied to the processing module by the transmission column.
