  • On-die voltage regulation using p-FET header devices with a feedback control loop
    Patent number: 8476966
    Abstract: The invention relates to a voltage regulator circuit for providing voltage to an integrated circuit chip, comprising a reference voltage generator providing a reference voltage, a pFET header device having a plurality of pFET fingers, wherein each pFET finger in the plurality of pFET fingers is adapted for providing a different pFET output voltage to the integrated circuit chip, and a pFET control device for switching the plurality of pFET fingers depending on a comparison between the reference voltage and the pFET output voltage. The voltage regulator circuit allows for dynamically switching on or off the pFET fingers based on the output of the comparison of the reference voltage and the pFET output voltage, and thus allows for dynamically switching on or off, respectively, at least partly the integrated circuit chip.
