Abstract: A microelectromechanical mirror device includes a supporting frame of semiconductor material and a plate of semiconductor material. The plate is connected to the supporting frame so as to be orientable around at least one rotation axis. A reflective layer is arranged on a first region of the plate. A piezoelectric actuation structure extends on a second region of the plate adjacent to the reflective layer. The piezoelectric actuation structure is configured to apply forces such as to modify a curvature of the plate.

Abstract: An electronic module includes a first die of semiconductor material including a first reflector, a second die of semiconductor material including a second reflector, and a frame including a first supporting portion and a second supporting portion parallel to one another. The first and second dies are carried, respectively, by the first and second supporting portions and are respectively arranged so that the first reflector faces the second supporting portion and the second reflector faces the first supporting portion. An incoming light beam impinges upon the first reflector and is reflected on the second reflector so as to be supplied at output from the electronic module.

Abstract: A delta-sigma modulation circuit has a sampling period and, in operation, generates a delta-sigma modulated signal based on the analog input signal. The delta-sigma modulation circuit includes: a first integrator; an analog-to-digital converter; a feedback-loop coupled between an input of the first integrator and the output interface; a second integrator coupled between the first integrator and the analog-to-digital converter. The delta-sigma modulation circuit has loop-delay compensation circuitry having a plurality of switches. The loop delay compensation circuitry, in operation, controls the plurality of switches based on a time interval of a duration of half the sampling period and generates a loop-delay compensation signal.

Abstract: A structural body made of semiconductor material includes an active area housing a drain region, a body region and a source region within the body region. An electrical-isolation trench extends in the structural body to surround the active area. A first PN-junction and a second PN-junction are integrated in the structural body between the active area and the trench, respectively located on opposite sides of the active area. The first and the second PN-junctions form a first diode and a second diode, with each diode having a respective cathode electrically coupled to the drain region of the MOSFET device and a respective anode electrically coupled to the source region of the MOSFET device.

Abstract: A tag adapted to be applied to an object is disclosed. The tag includes a wireless communication interface, a processor and a memory. A univocal code, a cipher key and a count value are store in the memory. The tag generates a dynamic code as a function of the cipher key and the count value. Next, the tag varies the count value according to a determined operation, and stores the varied count value in the memory. The tag transmits the univocal code and the dynamic code to a reader device. The tag may transmit the univocal code and the dynamic code in a URL.

Abstract: An integrated MOSFET device is formed in a body of silicon carbide and with a first type of conductivity. The body accommodates a first body region, with a second type of conductivity; a JFET region adjacent to the first body region; a first source region, with the first type of conductivity, extending into the interior of the first body region; an implanted structure, with the second type of conductivity, extending into the interior of the JFET region. An isolated gate structure lies partially over the first body region, the first source region and the JFET region. A first metallization layer extends over the first surface and forms, in direct contact with the implanted structure and with the JFET region, a JBS diode.
