Abstract: The present disclosure provides an electronic device that includes a substrate. The substrate includes a well and a peripheral insulating wall laterally surrounding the well. At least one lateral bipolar transistor is formed in the well, and the at least one transistor has a base region extending under parallel collector and emitter regions. The peripheral insulating wall is widened in a first direction, parallel to the collector and emitter regions, so that the base region penetrates into the peripheral insulating wall.

Abstract: A self-supporting thin-film battery is manufacture by forming on the upper surface of a support substrate a vertical active stack having as a lower layer a metal layer having formed therein a first contact terminal of a first polarity of the battery and having formed therein as an upper layer a metal layer having a second contact terminal of a second polarity of the battery. A support film is then bonded to an upper surface of the upper layer. The lower layer is the separated from the substrate by projecting a laser beam through the substrate from a lower surface thereof to impinge on the lower layer.

Abstract: A circuit includes a first field-effect transistor and a second field-effect transistor. The first field-effect transistor includes a first diode with drain, source, gate and first additional electrodes. The second field-effect transistor includes a second diode with drain, source, gate and second additional electrodes. A first switch selectively connects the gate and drain electrodes of the first field-effect transistor. A second switch selectively connects the gate and drain electrodes of the second field-effect transistor. A control circuit controls the first and second switches. The first additional electrode is coupled to the gate electrode of the second field-effect transistor, and the second additional electrode is coupled to the gate electrode of the first field-effect transistor.

Abstract: A thyristor or triac control circuit includes a first capacitive element that is series-connected with a first diode between a first terminal and a second terminal intended to be coupled to a gate of the thyristor or triac. A second capacitive element is coupled between the second terminal and a third terminal intended to be connected to a conduction terminal of the thyristor or triac on the gate side of the thyristor or triac. A second diode is coupled between the third terminal and a node of connection of the first capacitive element and first diode.

Abstract: A capacitor has a variable capacitance settable by a bias voltage. A method for setting the bias voltage including the steps of: (a) injecting a constant current to bias the capacitor; (b) measuring the capacitor voltage at the end of a time interval; (c) calculating the capacitance value obtained at the end of the time interval; (d) comparing this value with a desired value; and (e) repeating steps (a) to (d) so as long as the calculated value is different from the set point value. When calculated value matches the set point value; the measured capacitor voltage is stored as a bias voltage to be applied to the capacitor for setting the variable capacitance.

Abstract: A circuit for controlling an anode-gate thyristor includes a first transistor that couples a thyristor gate to a first terminal to receive a potential lower than a potential of a second terminal connected to the thyristor anode. A control terminal of the first transistor is driven by a control signal which is positive with respect to the potential of the first terminal.

Abstract: An assembly of batteries includes a first battery and a second battery electrically connected in parallel. The first battery is configured to deliver a battery capacity in a first power supply voltage range. The second battery is configured to deliver a battery capacity in a second voltage range. An upper limit of the second voltage range is set between upper and lower limits of the first voltage range. In an operating system, if supplied battery power falls below a threshold, the parallel connected first and second batteries are disconnected from the load.

Abstract: An AC/DC converter includes a first terminal and a second terminal to receive an AC voltage and a third terminal and a fourth terminal to deliver a DC voltage. A rectifying bridge is provided in the converter. A controllable switching or rectifying element has a control terminal configured to receive a control current. A first switch is coupled between a supply voltage and the control terminal to inject the control current. A second switch is coupled between the control terminal and a reference voltage to extract the control current. The first and second switches are selectively actuated by a control circuit.
