Abstract: A sensing bridge includes first and second branches in parallel, the first branch including a first resistor in series with a first switch, the second branch including a second resistor in series with a second switch. Resistances of the resistors vary with a sensed physical variable. The branches switch between first and second phases, with the first switch closed and the second switch open during the first phase, and the first switch open and the second switch closed during the second phase. A reference block generates a control signal from the resistance of the variable resistors during the first and second phases. An oscillator generates an oscillating signal during the first and second phases from the variable sense current during the first and second phases. Processing circuitry determines a value of the sensed physical value from an algebraic combination of the oscillating signal during the first and second phases.

Abstract: A pressure sensing device may include a body configured to distribute a load applied between first and second parts positioned one against the other, and a pressure sensor carried by the body. The pressure sensor may include a support body, and an IC die mounted with the support body and defining a cavity. The IC die may include pressure sensing circuitry responsive to bending associated with the cavity, and an IC interface coupled to the pressure sensing circuitry.

Abstract: First and second FETs of a half-bridge are series connected between first and second terminals and are gate driven, respectively, by first and second drivers. An inductance is connected to the intermediate node of the half-bridge. Power supply for the second driver circuit is a supply voltage generated by a voltage regulator as a function of the voltage between the first and the second terminal. Power supply for the first driver circuit is a supply voltage generated by a bootstrap capacitor having a first terminal connected via a first switch to receive the supply voltage output from the voltage regulator and a second terminal connected to the intermediate node. The first terminal of the bootstrap capacitor is further connected by a second switch to receive a second supply voltage. A control circuit generates control signals for the first and second driver circuits and the first and second switches.

Abstract: A voltage regulator and a phase change memory are disclosed. In an embodiment a phase-change memory includes an array of a plurality of phase-change memory cells, an address decoder configured for receiving an address signal and selecting a sub-area in the array of the plurality of memory cells, the selected sub-area having a given number of bits of a data signal and a writing circuit including a control circuit configured for receiving the data signal and determining, for each memory cell in the selected sub-area, whether a respective bit of the data signal indicates that the memory cell is to be changed from the amorphous state to the polycrystalline state and one or more driving circuits supplied via a regulated voltage and configured for applying the set current for the first interval to the memory cells that are to be changed from the amorphous state to the polycrystalline state.

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.
