Sherif Hosny 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).

  • Method, system and apparatus for accurate and stable LC-based reference oscillators
    Patent number: 8847695
    Abstract: A substantially temperature-independent LC-based oscillator is achieved using an LC tank that generates a tank oscillation at a phase substantially equal to a temperature null phase. The temperature null phase is a phase of the LC tank at which variations in frequency of an output oscillation of the LC-based oscillator with temperature changes are minimized. The LC-based oscillator further includes frequency stabilizer circuitry coupled to the LC tank to cause the LC tank to oscillate at the phase substantially equal to the temperature null phase.
    Type: Grant
    Filed: August 15, 2011
    Date of Patent: September 30, 2014
    Assignee: Si-Ware Systems
    Inventors: Bassel Hanafi, Sherif Hosny, Ayman Ahmed
