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.

Abstract: A device includes a number of irreversibly programmable memory points. Each irreversibly programmable memory point includes a first semiconductor zone and a gate located on the first zone. A conductive area defines the gates of the memory points. First and second semiconductor areas are respectively located on either side of a vertical alignment with the conductive area. The first zones are alternately in contact with the first and second areas.

Abstract: A system has an array of pixels including a plurality of active pixels and a plurality of dark reference pixels and processing circuitry coupled to the array of pixels. The processing circuitry sequentially computes, for each of a plurality of pairs of sets of dark reference pixels of the plurality of dark reference pixels, absolute differences in dark signal levels of the pair of sets of dark reference pixels. The absolute differences in dark signal levels are accumulated and a noise level of the dark reference pixels of the array of pixels is estimated based on the accumulated absolute differences. The system may be employed in, for example, a back-up camera of an automobile or a mobile phone.

Abstract: A ring oscillator includes a chain of logic components. A storage element is associated with each logic component and configured to store a state of an output of the logic component to which the storage element is associated. A first circuit counts state transitions of an output of a given logic component of the chain. A second circuit synchronizes each storage with a clock signal. A third circuit determines a number of logic components crossed by a state transition between two edges of the clock signal. This determination is made based on the counted number of state transitions and on the stored states of the outputs.

Abstract: An electronic device includes a module that delivers a positive temperature coefficient output voltage at an output terminal. A thermistor includes a first MOS transistor operating in weak inversion mode and having a negative temperature coefficient drain-source resistance and whose source is coupled to the output terminal. A current source coupled to the output terminal operates to impose the drain-source current of the first transistor.
