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 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: 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.

Abstract: In manufacturing a lithium battery, a plasma deposition of a layer of LiPON is made on a structure that includes an anode contact zone and a cathode contact zone. Before making the deposition of layer of LiPON, a conductive portion is deposited to short the anode contact zone to the cathode contact zone. After the deposition of the layer of LiPON in completed, the conductive portion is cut to sever the short between the anode and cathode contact zones.

Abstract: A filtering circuit includes at least two common-mode filters that are electrically coupled in series and magnetically coupled. The first common-mode filter includes first and second spiral inductors that are positively magnetically coupled and electrically isolated from each other. The second common-mode filter includes third and fourth spiral inductors that are positively magnetically coupled and electrically isolated from each other. The first and third spiral inductors are electrically connected in series and negatively magnetically coupled. Likewise, the second and fourth spiral inductors are electrically connected in series and negatively magnetically coupled.
