Abstract: 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.

Abstract: In an embodiment method, a hybrid coupler comprises a first input receiving an analog signal, a second input receiving an additional analog signal phase shifted by 90° from the analog signal, and first and second outputs. The method comprises injecting into the second output a test signal having an initial test phase, iteratively generating a current test phase for the test signal, from the initial test phase to a final test phase equal to the initial test phase increased by at least one portion of one complete revolution, and, in each iteration, measuring the current peak value of the first output, and storing the current test phase and the current peak value as a maximum/minimum peak value if there is not a stored maximum/minimum peak value higher/lower than the current peak value, respectively, and determining a phase of the analog signal from the stored test phase.

Abstract: In an embodiment, a method for determining the phase shift between a first signal and a second signal includes: delivering the first signal to a first input of a 90° hybrid coupler; delivering the second signal to a second input of the 90° hybrid coupler; determining a first piece of information relating to a power of a first output signal delivered to a first output of the 90° hybrid coupler; determining a second piece of information relating to a power of a second output signal delivered to a second output of the coupler; and adjusting the phase of the second signal until obtaining a calibrated phase for which the first piece of information is substantially equal to the second piece of information, wherein the first and second signals have identical frequencies, and wherein the phase shift between the first signal and the second signal is equal to the calibrated phase.
