Abstract: A semiconductor power device has: a die, with a front surface and a rear surface, and with an arrangement of projecting regions on the front surface, which define between them windows arranged within which are contact regions; and a package, which houses the die inside it. A metal frame has a top surface and a bottom surface; the die is carried by the frame on the top surface; an encapsulation coating coats the frame and the die. A first insulation multilayer is arranged above the die and is formed by an upper metal layer, a lower metal layer, and an intermediate insulating layer; the lower metal layer is shaped according to an arrangement of the projecting regions and has contact projections, which extend so as to electrically contact the contact regions, and insulation regions, interposed between the contact projections, in positions corresponding to the projecting regions.

Abstract: Blood pressure signals are reconstructed from PhotoPlethysmoGraphy (PPG) signals by: receiving PPG signals including systolic, diastolic and dicrotic phases; and determining first and second derivatives of the PPG signals and: a first set of values indicative of lengths of the signal paths of the PPG signal, the first derivative and the second derivative thereof in the systolic, diastolic and dicrotic phases; a second set of values indicative of relative durations of the PPG signal and the first and second derivatives thereof in the systolic, diastolic and dicrotic phases; and a third set of values indicative of the time separation of peaks and/or valleys in subsequent waveforms of the PPG signal. Reconstruction also includes applying artificial neural network processing to the first, second and third set of values. The artificial neural network processing includes artificial neural network training as a function of blood pressure signals to produce reconstructed blood pressure signals.

Abstract: The vertical-conduction electronic power device is formed by a body of wide band gap semiconductor which has a first conductivity type and has a surface, and is formed by a drift region and by a plurality of surface portions delimited by the surface. The electronic device is further formed by a plurality of first implanted regions having a second conductivity type, which extend into the drift region from the surface, and by a plurality of metal portions, which are arranged on the surface. Each metal portion is in Schottky contact with a respective surface portion of the plurality of surface portions so as to form a plurality of Schottky diodes formed by first Schottky diodes and second Schottky diodes, wherein the first Schottky diodes have, at equilibrium, a Schottky barrier having a height different from that of the second Schottky diodes.

Abstract: An embedded electronic system includes a volatile memory and a processor configured to execute a low-level operating system that manages allocation of areas of the volatile memory to a plurality of high-level operating systems. Each high-level operating system executes one or more applications. The system is configured so that execution data of one or a plurality of tasks of a first application are partly transferred, by the low-level operating system, from the volatile memory to a non-volatile memory when the execution of the task of the first application is interrupted by the execution of a task of a second application. The system is also configured so that the applications of any one of the high-level operating systems do not have access to the areas of the volatile memory allocated to the applications of all the other high-level operating systems.

Abstract: A radio-frequency receiver includes built-in-self-test (BIST) circuitry which generates a self-test signal. A local oscillator signal is divided. A self-test oscillation signal is generated, based, at least in part, on the frequency-divided local oscillation signal. The self-test signal is generated based on the self-test oscillation signal. The BIST circuitry includes a divider, which divides the self-test oscillation signal. The frequency-divided local oscillation signal and the divided self-test oscillation signal are used to perform one or more of generating the self-test oscillation signal and controlling the generation of the self-test oscillation signal. The radio-frequency receiver may be an automotive radar receiver.

Abstract: A MEMS actuator includes a main body having a central portion, couplable to a substrate, and a peripheral portion suspended over the substrate when the central portion is coupled to the substrate. The peripheral portion has a deformable structure extending around the central portion, and forming successively arranged membranes. The MEMS actuator includes bearing structures and corresponding piezoelectric actuators. The bearing structures are fixed at their top to the deformable structure and laterally delimit corresponding cavities, each having a lateral opening facing the central portion of the main body and closed at the top by a membrane. A fixed part of the membrane is fixed to the underlying bearing structure and a suspended part is laterally offset with respect to the underlying bearing structure. The piezoelectric actuators are controllable to cause deformation of the corresponding membrane and rotation of the bearing structures around the central portion of the main body.
