1. Structure for controlling the voltage applied to an integrated circuit which comprises:

  • a power supply;

    an integrated circuit including a temporal process monitor formed as part of said integrated circuit;

    a voltage controlled oscillator provided as part of said temporal process monitor for producing a first output signal having a first period; and

    a comparator for comparing said first period to one or more reference values;

    wherein said first period greater than a first selected reference value causes said comparator to send a signal to said power supply to increase the voltage being supplied to said integrated circuit and wherein said first period less than a second selected reference value causes said comparator to send a signal to said power supply to decrease the voltage applied to said integrated circuit.
