  • Patent number: 8341462
    Abstract: An automated method for provisioning a grid used to run a load test on a target website includes sending one or more requests in a multi-threaded manner to at least one cloud provider, the one or more requests for an allocation of N load server instances and M result server instances which comprise the grid. Requests received back from the cloud provider are also handled in a multi-threaded manner; any errors occurring during the allocation being corrected automatically. The N load server instances and the M result server instances are then verified to be operational and correctly running software deployed to provide defined test services. Errors identified during the verification are automatically corrected either by attempting to restart a failed instance or allocating a different instance.

  • Patent number: 8305826
    Abstract: A method for programming a programmable block of a power IC device includes selecting an anti-fuse element of the programmable block to be programmed. The anti-fuse element includes first and second capacitive plates separated by a dielectric layer. A voltage pulse is then applied to a pin of the power IC device. The pin is connected to a drain of a high-voltage field-effect transistor (HVFET) that drives an external load via the pin during a normal operating mode of the power IC device. The voltage pulse, which is coupled to the first capacitive plate of the anti-fuse element, has a potential sufficiently high to cause a current to flow through the anti-fuse element that destroys at least a portion of the dielectric layer, thereby electrically shorting the first and second capacitive plates.

  • Patent number: 8278994
    Abstract: A temperature independent reference circuit includes first and second bipolar transistors with commonly coupled bases. First and second resistors are coupled in series between the emitter of the second bipolar transistor and ground. The first and second resistors have first and second resistance values, R1 and R2, and third and second temperature coefficients, TC3 and TC2, respectively. The resistance values being such that a temperature coefficient of a difference between the base-emitter voltages of the first and second bipolar transistors, TC1, is substantially equal to TC2×(R2/(R1+R2))+TC3×(R1/(R1+R2)), resulting in a reference current flowing through each of the first and second bipolar transistors that is substantially constant over temperature. A third resistor coupled between a node and the collector of the second bipolar transistor has a value such that a reference voltage generated at the node is substantially constant over temperature.

  • Patent number: 8207580
    Abstract: In one embodiment, a power integrated circuit device includes a main lateral high-voltage field-effect transistor (HVFET) and an adjacently-located lateral sense FET, both of which are formed on a high-resistivity substrate. A sense resistor is formed in a well region disposed in an area of the substrate between the HVFET and the sense FET. A parasitic substrate resistor is formed in parallel electrical connection with the sense resistor between the source regions of the HVFET and the sense FET. Both transistor devices share common drain and gate electrodes. When the main lateral HVFET and the sense FET are in an on-state, a voltage potential is produced at the second source metal layer that is proportional to a first current flowing through the lateral HVFET.

  • Patent number: 8164125
    Abstract: A semiconductor device includes an N type well region in a P type substrate. A source region of a MOSFET is laterally separated from a boundary of the well region, which includes the drain of the MOSFET. An insulated gate of the MOSFET extends laterally from the source region to at least just past the boundary of the well region. A polysilicon layer, which forms a first plate of a capacitive anti-fuse, is insulated from an area of the well region, which forms the second plate of the anti-fuse.
