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 circuit includes first, second, and third 90° hybrid couplers coupled between first and second antenna terminals, a pair of low-noise amplifiers (LNAs), and a pair of power amplifiers (PAs). The pair of LNAs is configured to receive first signals from the first and second antenna terminals and has an output configured to be coupled to a receive path. The second coupler is configured in power combiner mode for receiving the first signals. The pair of PAs is configured to transmit second signals via the first and second antenna terminals and has an input configured to be coupled to a transmit path. The third coupler is configured in power divider mode for transmitting the second signals.

Abstract: An electronic envelope detection circuit includes an input signal detecting circuit having at least one MOS transistor configured to receive a radiofrequency input signal and to deliver an internal signal on the basis of the input signal. The biasing point of the at least one transistor is controlled by the input signal and a control signal. A processing circuit that is coupled to the input signal detecting circuit is configured to deliver a low-frequency output signal on the basis of the internal signal and further deliver the control signal on the basis of the output signal. In operation, the value of the control signal decreases when the average power of the input signal increases, and vice versa.

Abstract: A semiconductor substrate includes a doped region having an upper surface. The doped region may comprise a conduction terminal of a diode (such as cathode) or a transistor (such as a drain). A silicide layer is provided at the doped region. The silicide layer has an area that only partially covers an area of the upper surface of the doped region. The partial area coverage facilitates modulating the threshold voltage and/or leakage current of an integrated circuit device.

Abstract: The present description concerns a method of manufacturing a first wafer, intended to be assembled to a second wafer by molecular bonding, including the successive steps of: forming a stack of layers at the surface of a substrate; and successive chemical etchings of the edges of said layers from the layer of the stack most distant from the substrate, across a smaller and smaller width.

Abstract: The method of determination of a depth map of a scene comprises generation of a distance map of the scene obtained by time of flight measurements, acquisition of two images of the scene from two different viewpoints, and stereoscopic processing of the two images taking into account the distance map. The generation of the distance map includes generation of distance histograms acquisition zone by acquisition zone of the scene, and the stereoscopic processing includes, for each region of the depth map corresponding to an acquisition zone, elementary processing taking into account the corresponding histogram.
