Abstract: An embodiment method comprises collecting at least one electrophysiological signal of a human over a limited time duration, and computing a set of electrophysiological signal features. The computing comprises at least one of: providing at least one reference electrophysiological signal and applying dynamic time warping processing to the at least one collected and at least one reference electrophysiological signals, applying stacked-auto-encoder artificial neural network processing to the collected electrophysiological signal, or filtering the electrophysiological signal collected via joint low-pass and high-pass filtering. The method further comprises applying pattern recognition processing to the computed set of features, producing a virtual key signal indicative of an identity of the human, and applying the virtual key signal to a user circuit to switch it between a first state and a second state as a result of the virtual key signal matching an authorized key signal stored in the user circuit.

Abstract: A multiple-input analog-to-digital converter device includes analog-to-digital converter circuits arranged between input nodes and output nodes. The analog-to-digital converter circuits operate over respective conversion times to provide simultaneous conversion of the analog input signals into respective conversion time signals. A time-to-digital converter circuit includes timer circuitry common to the plurality of analog-to-digital converter circuits. The timer circuitry cooperates with the analog-to-digital converter circuits to convert the conversion time signals into digital output signals at the output nodes.

Abstract: A radio-frequency transceiver device includes a transmission circuit generating a transmission signal at a transmission pad connected to a transmission antenna by modulating a radio frequency signal as a function of a control signal. First and second reception circuits receive first and second signals at first and second reception pads connected to first and second reception antennas. The received first and second signals are demodulated via the radio frequency signal to generate first and second demodulated reception signals. A control circuit operates during a reception test phase to generate only the control signal in order to test, as a function of the first and second demodulated reception signals, whether the received first signal corresponds to the received second signal. A reception error signal indicating a reception error is generated when the test indicates that the received first and second reception signals do not correspond.

Abstract: A circuit for controlling a first plurality of transistors connected in parallel and a second plurality of transistors connected in parallel, includes: a first plurality of stages, a respective one of the first plurality of stages being configured to supply a first control signal to a respective one of the first plurality of transistors; and a second plurality of stages, a respective one of the second plurality of stages being configured to supply a second control signal to a respective one of the second plurality of transistors. An output current of the respective one of the first plurality of stages is regulated based on a difference between a first value representative of a sum of output currents of each stage of the first plurality of stages and a second value representative of a sum of set points assigned to the first plurality of stages.

Abstract: In various embodiments, the present disclosure provides capacitors and methods of forming capacitors. In one embodiment, a capacitor includes a substrate, a first electrode on the substrate, a second electrode, and a first dielectric layer. A portion of the first electrode is exposed in a contact region. The first dielectric layer includes a first dielectric region between the first electrode and the second electrode, and a second dielectric region between the first dielectric region and the contact region. The second dielectric region is contiguous to the first dielectric region, and a surface of the second dielectric region defines a surface path between the first electrode and the contact region. The second dielectric region has a plurality of grooves that increase a spatial extension of said surface path.

Abstract: An oscillating structure includes first and second torsional elastic elements that define an axis of rotation and a moving element that is interposed between the first and second torsional elastic elements. The moving element, the first torsional elastic element and the second torsional elastic element lie in a first plane and are not in direct contact with one another. A coupling structure mechanically couples the moving element, the first torsional elastic element and the second torsional elastic element together. The moving element, the first torsional elastic element and the second torsional elastic element lie in a second plane different from the first plane. Oscillation of the moving element occurs as a result of a twisting of the first and second torsional elastic elements.

Abstract: A power semiconductor device including a first and second die, each including a plurality of conductive contact regions and a passivation region including a number of projecting dielectric regions and a number of windows. Adjacent windows are separated by a corresponding projecting dielectric region with each conductive contact region arranged within a corresponding window. A package of the surface mount type houses the first and second dice. The package includes a first bottom insulation multilayer and a second bottom insulation multilayer carrying, respectively, the first and second dice. A covering metal layer is arranged on top of the first and second dice and includes projecting metal regions extending into the windows to couple electrically with corresponding conductive contact regions. The covering metal layer moreover forms a number of cavities, which are interposed between the projecting metal regions so as to overlie corresponding projecting dielectric regions.
