摘要： In a power supply having a control circuit for regulating the power supply output and a load switch for connecting the output to a load device, a method for reducing standby power includes determining if a load device is connected to the power supply. If no load device is connected, the load switch is turned off, and the power supply enters a standby mode, which includes alternating first time period of power-saving mode and second time period of regulating mode. In the power-saving mode, the control circuit stops regulating the output of the power supply and turns off one or more functional blocks to allow the output to drop, until the output reaches a pre-set low output limit. In the regulating mode, the control circuit turns on the functional blocks and regulates the power supply to allow the output to increase, until the output reaches a pre-set high output limit.

摘要： The invention solves the problem of depressed SOA of a bipolar junction transistor (BJT) when operated in an open base configuration by integrating in the same semiconductor chip a switchable short between the base and the emitter of the BJT. The switchable short switches between a high resistive value when the collector voltage of the BJT is lower than the base voltage. and a lower resistive value when the collector voltage is higher than the voltage base to effectively lower the BJT current gain (hFE). The switchable short in one implementation of the invention is in the form of a MOSFET with its gate connected to the BJT collector. The invention further teaches disposing in the integrated circuit chip a junction diode with a breakdown voltage lower than the BVCBO of the BJT. The addition of the junction diode provides a measure of maintaining the effectiveness of the MOSFET as switchable short at a reduced size.

摘要： TSV devices with p-n junctions that are planar have superior performance in breakdown and current handling. Junction diode assembly formed in enclosed trenches occupies less chip area compared with junction-isolation diode assembly in the known art. Diode assembly fabricated with trenches formed after the junction formation reduces fabrication cost and masking steps increase process flexibility and enable asymmetrical TSV and uni-directional TSV functions.

摘要： Some embodiments of the present disclosure provide the design and manufacture of an ultra-small chip assembly. The ultra-small chip assembly comprises a die, a plate-like back electrode disposed on the back-side of the die, and one or more plate-like positive electrodes disposed on the front-side of the die. The ultra-small chip assembly is configured such that one end of the plate-like back electrode extends beyond a first side of the die, and each of the one or more plate-like positive electrodes includes an end which extends beyond a second side of the die. By attaching both the plate-like back electrode and the plate-like positive electrodes on the surfaces of the die, and directly using the exposed ends of the plate-like electrodes as the lead-out electrodes for the chip assembly, the electrical connections outside of the die only occupy a very small volume.
