  • Patent number: 11336172
    Abstract: A control unit for a switching converter has an inductor element coupled to an input and a switch element coupled to the inductor element and generates a command signal having a switching period to switch the switch element and determine a first time period in which an inductor current is flowing in the inductor element for storing energy and a second time period in which energy is transferred to a load. An input current is distorted relative to a sinusoid by a distortion factor caused by current ripple on the inductor current. The duration of the first time period is determined based on a comparison between a peak value of the inductor current and a current reference that is a function of an output voltage of said voltage converter. A reference modification stage modifies one of the current reference and sensed value of the inductor current to compensate for distortion introduced by the distortion factor on the input current.

  • Patent number: 11327295
    Abstract: A MEMS device is formed in a die of semiconductor material having a cavity defined therein and having an anchorage portion. A tiltable structure is elastically suspended over the cavity and has a main extension in a horizontal plane. First and second supporting arms extend between the anchorage portion and opposite sides of the tiltable structure. First and second resonant piezoelectric actuation structures are intended to be biased to thereby cause rotation of the tiltable structure about a rotation axis. The first supporting arm is formed by first and second torsion springs, which are rigid to movements out of the horizontal plane and compliant to torsion about the rotation axis and are coupled together at a constraint region. The first and second resonant piezoelectric actuation structures extend between the anchorage portion and the constraint structure, on first and second sides of the first supporting arm.

  • Patent number: 11329011
    Abstract: An integrated circuit is protected against at attack. An electrically conductive body at floating potential is situated in the integrated circuit. The electrically conductive body has an initial amount of electric charge prior to the attack and functions to collect electric charge as a result of the attack. A detection circuit operates to detect an amount of electric charge collected on the electrically conductive body and determine whether the collected amount is different from the initial amount. If the detected amount of charge is different from the initial amount, a control circuit trigger the taking of a protective action.
