    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.

    Abstract: A rectifying element includes a MOS transistor series-connected with a Schottky diode. A bias voltage is applied between the control terminal of the MOS transistor and the terminal of the Schottky diode opposite to the transistor. A pair of the rectifying elements are substituted for diodes of a rectifying bridge circuit. Alternatively, the control terminal bias is supplied from a cross-coupling against the Schottky diodes. In another implementation, the Schottky diodes are omitted and the bias voltage applied to control terminals of the MOS transistors is switched in response to cross-coupled divided source-drain voltages of the MOS transistors. The circuits form components of a power converter.

    Abstract: A digital-to-analog converter (DAC) and a method for operating the DAC are disclosed. The DAC receives, over a first channel, a control signal that is transmitted in accordance with a binary protocol. The DAC also receives, over a second channel different than the first channel, data that is transmitted in accordance with a multilevel communication protocol that is different than the binary protocol. The DAC determines a plurality of first and second voltages based on the received data and identifies, based on the control signal, a time when data transmission or reception is switched between first and second antennas. In response to identifying, based on the control signal, the time when data transmission or reception is switched, the DAC outputs the determined plurality of first voltages to a first antenna tuning circuit or the determined plurality of second voltages to a second antenna tuning circuit.

    Abstract: An electronic device includes a flexible conductive member having a first length, and a battery substrate having a second length shorter or equal than the first length. There is an active battery on the battery substrate. An adhesive layer couples the active battery and the battery substrate to the flexible conductive member such that the active battery and the flexible conductive member are electrically coupled, and such that the flexible substrate encapsulates the active battery and the upper portion of the battery substrate without an intervening layer. The flexible conductive member includes an insulating flexible base layer having a conductive via formed therein. Upper and lower metallized layers are formed on the insulating flexible base layer and are electrically coupled to one another by the conductive via.
