RAFAEL PAYSEO-DIAZ has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • APPARATUS AND METHOD FOR CONTROLLING THE PROPAGATION DELAY OF A CIRCUIT BY CONTROLLING THE VOLTAGE APPLIED TO THE CIRCUIT
    Publication number: 20080278223
    Abstract: The voltage applied to an integrated circuit is controlled by a temporal process monitor formed as part of the integrated circuit. The temporal process monitor includes a voltage controlled oscillator for producing a first output signal having a first period. A comparator compares the first period to one or more reference values. Should the first period be greater than a first selected reference value the comparator sends a signal to increase the voltage being supplied to the integrated circuit. Should the first period be less than a second selected reference value, the comparator sends a signal to decrease the voltage applied to the integrated circuit. In some embodiments a scaling circuit is provided for producing a second output signal having a second period different from (typically but not necessarily longer than) the first period.
