    Abstract: An integrated circuit chip is mounted to a front face of a support plate. An encapsulation cap in then mounted to the support plate. The encapsulation cap includes a front wall and a peripheral wall having an end edge at least partly facing a peripheral zone of the support plate. The support plate and the encapsulation cap delimit a chamber in which the integrated circuit chip is situated. To mount the encapsulation cap, a bead of glue is inserted between the peripheral zone and the end edge of the peripheral wall of the encapsulation cap. A peripheral outer face of the encapsulation cap includes a recess extending from the end edge which locally uncovers a part of the bead of glue. A local hardening of the glue at the recess is performed as a first attachment step. Further hardening of the remainder of the glue is then performed.

    Abstract: A system includes a near-field communication device configured to transmit a radio frequency control signal in a near-field regime and an interface. The interface includes a near-field communication circuit configured to receive the RF control signal. The interface further includes a pulse width modulation signal generation circuit configured to generate a pulse width modulation signal according to the radio frequency control signal. The system further includes an electrically-controllable equipment configured to be controlled by the pulse width modulation signal.

    Abstract: Individual electronic units are formed by cutting a collective assembly. A collective support plate is provided which includes electronic chips. A collective cover plate is provided which includes ribs defining recesses. The collective assembly is formed by mounting the collective cover plate to the collective support plate in a manner where the electronic chips are located in the recesses and the ribs are located between electronic chips. A bead of glue is interposed between ends of the ribs and the surface of the collective support plate. After the glue is hardened, a cutting operation is performed on the collective assembly by cutting through the ribs and the collective support plate to produce the individual electronic units.

    Abstract: A method of reducing noise generated by pulse width modulation (PWM) signals includes generating a PWM pulse train using a first set of parameter values and modifying the PWM pulse train during a near-field communication so that the PWM pulse train is generated using a second set of parameter values. Modifying the PWM pulse train includes reducing at least one parameter value of the first set of parameter values. The method further includes resuming generation of the PWM pulse train using the first set of parameter values after the near-field communication.

    Abstract: A USB source device, supporting USB Power Delivery mode and coupled to a USB receiver device, includes a power converter delivering a supply voltage and a capacitive network coupled to the power converter. A method for managing the supply voltage on an output power supply pin of the USB source device includes discharging the capacitive network so as to reduce the supply voltage in response to a request to reduce the supply voltage by the USB receiver device to a target voltage. The method also includes delivering, to the power converter, a setpoint voltage for the supply voltage, a value of the setpoint voltage being reduced non-linearly so as to keep a temporal variation of the setpoint voltage lower than that of the supply voltage.
