Abstract: An energy-scavenging interface includes first and second switches connected in series between an input and reference, and third and fourth switches connected in series between the input and an output. A control circuit closes the first and second switches and opens the third switch for a first time interval to store charge in a storage element. A scaled copy of a peak value of the charging current is obtained. The control circuit then opens the first switch and closes the third and fourth switches to generate an output signal as long as the value in current of the output signal is higher than the value of said scaled copy of the peak value.

Abstract: In an embodiment, access transactions of at least one module of a system such as a System-on-Chip (SoC) to one of a plurality of target modules, such as memories, are managed by assigning transactions identifiers subjected to a consistency check. If an input identifier to the check has already been issued for the same given target module, to the related identifier/given target module pair the same input identifier is assigned as a consistent output identifier. If, on the contrary, said input identifier to the check has not been already issued or has already been issued for a target module different from the considered one, to the related identifier/given target module pair a new identifier, different from the input identifier, is assigned as a consistent output identifier.

Abstract: A band-pass filter made up by an operational amplifier and by an input circuit. The input circuit is formed by a capacitive filtering element, connected to the input of the operational amplifier; a coupling switch, coupled between an input node and the capacitive filtering element; a capacitive sampling element, coupled between the input of the filter and the input node; and a sampling switch, coupled between the input node and a reference-potential line. The coupling switch and the input sampling switch close in phase opposition according to a succession of undesired components sampling and sensing steps, so that the capacitive sampling element forms a sampler for sampling the undesired component in the undesired components sampling step, in the absence of the component of interest, and forms a subtractor of the undesired components from the input signal in the sensing step.

Abstract: An inertial sensor having a body with an excitation coil and a first sensing coil extending along a first axis. A suspended mass includes a magnetic-field concentrator, in a position corresponding to the excitation coil, and configured for displacing by inertia in a plane along the first axis. A supply and sensing circuit is electrically coupled to the excitation coil and to the first sensing coil, and is configured for generating a time-variable flow of electric current that flows in the excitation coil so as to generate a magnetic field that interacts with the magnetic-field concentrator to induce a voltage/current in the sensing coil. The integrated circuit is configured for measuring a value of the voltage/current induced in the first sensing coil so as to detect a quantity associated to the displacement of the suspended mass along the first axis.
