  • Voltage regulator
    Patent number: 9705393
    Abstract: A method of operating a voltage regulator including a source voltage rail and a plurality of output voltage rails, the method including: converting a source voltage on the source voltage rail to a respective output voltage on each output voltage rail; selecting an output voltage rail; comparing the output voltage on the selected output voltage rail to a reference voltage for the selected output voltage rail; and if the output voltage of the selected output voltage rail is less than the reference voltage for the selected output voltage rail, controlling the voltage regulator to increase the output voltage on the selected output voltage rail, wherein the frequency at which an output voltage rail is selected is dependent upon the rate at which the voltage regulator has previously increased the output voltage on that output voltage rail.

  • Integrated circuit operating active circuitry and chip pads in different operating modes and at different voltage levels
    Patent number: 9331673
    Abstract: An integrated circuit having an external connection pad and an active circuit for generating signals to be output from the integrated circuit by means of the pad, the integrated circuit including an interface circuit associated with the pad, the interface circuit including a latch coupled between the pad and an output of the active circuit, the latch being capable of operating in a first mode in which the state of the pad follows the state of the output of the active circuit and a second mode in which the state of the pad is held by the latch.

  • Device security
    Patent number: 8818335
    Abstract: A functional device includes a local wireless transceiver for communicating with a remote wireless transceiver through a protocol according to which the local transceiver maintains a record of its connection state with selected devices that are within range of it. The device includes a memory for storing the identity of a selected device; and a controller configured to inhibit one or more functions of the functional device if the connection state maintained by the transceiver is indicative of the selected device being out of range. The performance of the functions of the device is independent of the local wireless transceiver.
