James P. Maligeorgos 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).

  • Controlling the frequency of an oscillator
    Patent number: 7689190
    Abstract: A technique includes generating an analog voltage to control a frequency for an oscillator. The analog signal is converted into a digital signal, and the frequency is controlled in response to the digital signal.
    Type: Grant

  • Controlling the frequency of an oscillator
    Patent number: 7536164
    Abstract: A technique includes selectively coupling impedances to an oscillator to establish a first frequency of operation of the oscillator. The technique includes repeating the selective coupling in a feedback loop to cause the first frequency to be near a second frequency.

  • Capacitor array segmentation
    Patent number: 7280001
    Abstract: In one embodiment, the present invention includes a capacitor array that may provide a selected capacitance to a digitally controlled crystal oscillator (DCXO). The array may include multiple sections each having at least one array portion, where each section is to receive different significant portions of a digital control value. The different sections may have different coding schemes. Other embodiments are described and claimed.
