  • Power supply scheme for reduced power compensation
    Patent number: 8063508
    Abstract: A power control system is described that reuses current from segregated circuits of the mobile device. In some embodiments, the segregated circuits (or “sections”) can be “stacked” in series (with respect to the power supply) such that power is more efficiently used. The power can be more efficiently used by arranging a first section to reuse current that supplies power to a second section. A power control unit can be used to control regulators.
    Type: Grant
    Filed: December 24, 2009
    Date of Patent: November 22, 2011
    Assignee: Infineon Technologies AG
    Inventors: Christian Grewing, Stefan Heinrich van Waasen

  • VCO Pre-Compensation
    Publication number: 20090206939
    Abstract: A VCO device is described that has pre-compensation. Digitally switchable compensation capacitors are selectively activated to adjust operation of the VCO to mitigate undesirable operational effects. In some example embodiments, the digitally switchable compensation capacitors of the VCO are adjusted to compensate for the effects of activating (from a quiescent state) an output buffer driven by the VCO.
