Abstract: A method can be performed prior to implementation of a neural network by a processing unit. The neural network comprising a succession of layers and at least one operator applied between at least one pair of successive layers. A computational tool generates an executable code intended to be executed by the processing unit in order to implement the neural network. The computational tool generates at least one transfer function between the at least one pair of layers taking the form of a set of pre-computed values.

Abstract: An active discharge circuit discharges an X capacitor and includes a sensor circuit that generates a sensor signal indicative of an AC voltage at the X capacitor. A processing unit generates a reset signal as a function of a comparison signal. A comparator circuit generates the comparison signal by comparing the sensor signal with a threshold. A timer circuit sets a discharge enable signal to a first logic level when the timer circuit is reset via a reset signal. The timer circuit determines the time elapsed since the last reset and tests whether the time elapsed exceeds a given timeout value. If the time elapsed exceeds the given timeout value, the timer circuit sets the discharge enable signal to a second logic level. A dynamic threshold generator circuit varies the threshold of the comparator circuit as a function of the sensor signal.

Abstract: A first switch couples an input node receiving a main control signal for a main switching stage of a multi-phase converter to an output node delivering a secondary control signal for a secondary switching stage following actuation of the secondary switching stage. A second switch couples the output node to a capacitor during a time period of actuation/deactuation of the secondary switching stage. Current is sourced to the capacitor during the actuation time period or sunk from the capacitor during the deactuation time period. The sourced or sunk current may be generated proportional to the main control signal.

Abstract: A method of operating a gas sensing device is described. The method includes receiving a signal indicative of a value of resistance of a gas sensing element, processing the signal received to compute a value of a gas concentration, performing a comparison of the value of gas concentration to a threshold, and, based on the outcome of a diagnosis procedure, setting the device to an alert signal issue state as a function of the outcome of the comparison. The diagnosis procedure includes computing a set of parameters indicative of the state of the gas sensor circuit, and classifying the gas sensor circuit in one of a first, a second and a third class based on the parameters.

Abstract: A MEMS resonator system has a micromechanical resonant structure and an electronic processing circuit including a first resonant loop that excites a first vibrational mode of the structure and generates a first signal at a first resonance frequency. A compensation module compensates, as a function of a measurement of temperature variation, a first variation of the first resonance frequency caused by the temperature variation to generate a clock signal at a desired frequency that is stable relative to temperature. The electronic processing circuit further includes a second resonant loop, which excites a second vibrational mode of the structure and generates a second signal at a second resonance frequency. A temperature-sensing module receives the first and second signals and generates the measurement of temperature variation as a function of the first variation of the first resonance frequency and a second variation of the second resonance frequency caused by the temperature variation.

Abstract: A device includes serial cyclic redundancy check (CRC) processing circuitry and parallel CRC processing circuitry. The serial CRS processing circuitry, in operation, generates a set of intermediate CRC bits based on a first set of seed bits and input data. The parallel CRC processing circuitry is coupled to the serial CRC processing circuitry, and, in operation, generates, using the set of intermediate CRC bits as a set of parallel seed bits and using null input bits, a set of output CRC bits corresponding to the input data.

Abstract: A micro-heater element for a MEMS sensor device, envisages, in a single conductive layer: an outer ring, defining inside it a window; a heat-diffusion structure, arranged within the window, separated from the outer ring by a first separation gap; and connection elements, arranged between the heat-diffusion structure and the outer ring, and designed to connect the heat-diffusion structure to the outer ring. The outer ring is designed to dissipate energy upon passage of an electric current, and the heat-diffusion structure is designed to distribute, within the micro-heater element, the heat that is transferred by the outer ring through the connection elements.

Abstract: An electronic device comprising: a semiconductor body of silicon carbide, SiC, having a first and a second face, opposite to one another along a first direction, which presents positive-charge carriers at said first face that form a positive interface charge; a first conduction terminal, which extends at the first face of the semiconductor body; a second conduction terminal, which extends on the second face of the semiconductor body; a channel region in the semiconductor body, configured to house, in use, a flow of electrons between the first conduction terminal and the second conduction terminal; and a trapping layer, of insulating material, which extends in electrical contact with the semiconductor body at said channel region and is designed so as to present electron-trapping states that generate a negative charge such as to balance, at least in part, said positive interface charge.
