Abstract: The MEMS gyroscope has a mobile mass carried by a supporting structure to move in a driving direction and in a first sensing direction, perpendicular to each other. A driving structure governs movement of the mobile mass in the driving direction at a driving frequency. A movement sensing structure is coupled to the mobile mass and detects the movement of the mobile mass in the sensing direction. A quadrature-injection structure is coupled to the mobile mass and causes a first and a second movement of the mobile mass in the sensing direction in a first calibration half-period and, respectively, a second calibration half-period. The movement-sensing structure supplies a sensing signal having an amplitude switching between a first and a second value that depend upon the movement of the mobile mass as a result of an external angular velocity and of the first and second quadrature movements. The first and second values of the sensing signal are subtracted from each other and compared with a stored difference value to supply information of variation of the scale factor.

Abstract: In an embodiment, PhotoPlethysmoGraphy (PPG) signals are processed by detecting peaks and valleys in the PPG signal, segmenting the PPG signal to provide a time series of PPG waveforms located between two subsequent valleys in the PPG signal, applying to the waveforms in the time series pattern recognition with respect to a reference PPG waveform pattern produced based on a mathematical model of the PPG signal by assigning to the waveforms in the time series a recognition score. A resulting PPG signal is produced by retaining the waveforms in the time series having an assigned recognition score reaching a recognition threshold, and discarding the waveforms in the time series having an assigned recognition score failing to reach the recognition threshold.

Abstract: A control circuit for a voltage source generates a reference signal for a voltage source, wherein the reference signal indicates a requested output voltage to be generated by the voltage source. A digital feed-forward control circuit computes a digital feed-forward regulation value indicative of a requested output voltage by determining a maximum voltage drop at strings of solid-state light sources. A digital feed-back control circuit determines a minimum voltage drop for current regulators/limiters for the strings and determines a digital feed-back correction value as a function of the minimum voltage drop. The control circuit then sets the reference signal after a start-up as a function of the digital feed-forward regulation value and corrects the reference signal as a function of the digital feed-back correction value.

Abstract: A half-bridge control circuit comprises an input terminal, an output terminal for providing a pulsed signal to a half-bridge driver circuit configured to drive two electronic switches connected between two supply terminals, and a feedback terminal for receiving a feedback signal indicative of the instantaneous voltage value at a switching node between the two electronic switches. A selector circuit provides a digital feedback signal. A subtractor generates an error signal by subtracting the digital feedback signal from the reference signal. An integrator generates an integration signal by integrating the value of the error signal. A down-scale circuit generates a reduced resolution integration signal by discarding one or more least significant bits of the integration signal. A sampling circuit generates a sampled integration signal by sampling the reduced resolution integration signal. A pulse generator circuit generates the pulsed signal as a function of the sampled integration signal.

Abstract: A circuit receives an input signal having a first level and a second level. A logic circuit includes a finite state machine circuit, an edge detector circuit, and a timer circuit. The finite state machine circuit is configured to set a mode of operation of the circuit. The edge detector circuit is configured to detect a transition between the first and second level. The timer circuit is configured to determine whether the first or second level is maintained over an interval, which starts from a transition detected by the edge detector circuit. The finite state machine circuit is configured to change the mode of operation based on the timer circuit determining that the first or second level has been maintained over the interval.

Abstract: A MOSFET device includes a semiconductor body having a first and a second face. A source terminal of the MOSFET device includes a doped region which extends at the first face of the semiconductor body and a metal layer electrically coupled to the doped region. A drain terminal extends at the second face of the semiconductor body. The doped region includes a first sub-region having a first doping level and a first depth, and a second sub-region having a second doping level and a second depth. At least one among the second doping level and the second maximum depth has a value which is higher than a respective value of the first doping level and the first maximum depth. The metal layer is in electrical contact with the source terminal exclusively through the second sub-region.

Abstract: In an embodiment, the column decoder of a PCM device is divided into two portions that can be governed independently of one another, and the driving signals of the two portions are configured so as to guarantee comparable capacitive loads at the two inputs of a sense amplifier in both of the operations of single-ended reading and double-ended reading. In particular, during single-ended reading, the sense amplifier has a first input that receives a capacitive load corresponding to the direct memory cell selected, and a second input that receives a capacitive load associated to a non-selected complementary memory cell.
