摘要： A reception element receives an analog signal. The received analog signal is converted by a reception chain into a digital signal. Based on the digital signal and a first filtering operation, a correction chain generates a correction digital signal reconstituting dynamic nonlinearities generated by the reception chain. A corrected signal from which the reconstituted dynamic nonlinearities have been removed is then generated by subtracting the correction digital signal from the digital signal.

摘要： An electronic device includes a doped semiconductor substrate of a first conductivity type. A first doped well of a second conductivity type opposite to the first conductivity type extends into the doped semiconductor substrate from a surface thereof. A second doped well of the first conductivity type is located in the first well. A third electrically-insulating well is located in the second well. A fourth doped well of the first conductivity type is located in the third well. First, second, and third doped regions of the first conductivity type are respectively located in the doped semiconductor substrate, the second doped well and the fourth doped well. The first, second, and third doped regions have doping levels greater than a doping level of the doped semiconductor substrate. A fourth doped region the second conductivity type is located in the fourth doped well adjacent the second doped region.

摘要： A contactless communication method comprises retro-modulation of a carrier signal received at the terminals of an antenna in an alternation of modulated states and unmodulated states. The modulated state comprises a modulation of a load at the terminals of the antenna at zero impedance, and the transitions from the modulated state to the unmodulated state are controlled at an instant determined by a first delay.

摘要： A device includes an active semiconductor layer on top of and in contact with an insulating layer which overlies a semiconductor substrate. A transistor for the device includes a source region, a drain region, and a body region arranged in the active semiconductor layer. The body region of the transistor is electrically coupled to the semiconductor substrate using a conductive via that crosses through the insulating layer.

摘要： An X-ray detector includes a first circuit with an NPN-type bipolar transistor and a second circuit configured to compare a voltage at a terminal of the NPN-type bipolar transistor with a reference value substantially equal to a value of the terminal voltage which would occur when the first circuit has been exposed to a threshold quantity of X-rays.

摘要： The present disclosure concerns an electronic device connected to an antenna. The electronic device delivers a first amplitude-modulated analog signal of a signal captured by the antenna, the capture signal associated with an electromagnetic field exhibiting intervals at a minimum level. The electronic device includes a first circuit, a second circuit, and a third circuit. The first circuit delivers a second analog signal by rectification and filters the first analog signal. The second circuit delivers a first binary signal based on the demodulation of the second analog signal. The third circuit couples the antenna to a resistor during each pause. The resistance value of the resistor depends on the maximum amplitude of the electromagnetic field before the pause.
