Patents by Inventor Usman Azeez Mughal

Usman Azeez Mughal 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).

  • Variable lock window for a phase locked loop
    Patent number: 6614317
    Abstract: A lock detector system which operates adaptively based on a frequency of operation. Different lock windows are defined for different frequencies of operation and are automatically formed based on the controlled signal that is used to drive the voltage controlled oscillator of the phase locked loop.
    Type: Grant
    Filed: May 24, 2001
    Date of Patent: September 2, 2003
    Assignee: Intel Corporation
    Inventors: Keng L. Wong, Usman Azeez Mughal, Masud Kamal, Chee How Lim, Kent R. Callahan
  • Bus termination scheme for flexible uni-processor and dual processor platforms
    Patent number: 6522165
    Abstract: A circuit board has a transmission line. A connector is coupled to the circuit board and electrically coupled to the transmission line. Bus termination circuitry is electrically coupled to the transmission line at or near an end of the transmission line at the connector such that the transmission line is terminated by the bus termination circuitry when the connector is not engaged to support any device for electrical coupling to the transmission line.
    Type: Grant

  • Circuit compensation technique
    Patent number: 6509780
    Abstract: A technique for compensating a characteristic, such as a resistance, of at least one circuit includes selectively incrementing a characteristic of a dummy circuit and comparing it with a characteristic of an external reference to generate a reference code. A previous reference code is stored and subsequently compared with a present reference code. It is ensured that the present reference code differs by no more than a predetermined amount from the stored previous reference code by ceasing the incrementing or decrementing of the characteristic of the dummy circuit and utilizing the present reference code to compensate the characteristic of the at least one circuit.
