Patents by Inventor Amr G. Elgamal

Amr G. Elgamal 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 METHODS FOR COMPENSATING SUPPLY SENSITIVE CIRCUITS FOR SUPPLY VOLTAGE VARIATION
    Publication number: 20230376064
    Abstract: Apparatus and methods for compensating supply sensitive circuits for supply voltage variation are provided. In certain embodiments, an electronic system includes a power supply that outputs a supply voltage having a nominal voltage level, a supply conductor for routing the supply voltage, and a group of integrated circuits (ICs) that each receive the supply voltage from the supply conductor. Each IC includes a supply sensing circuit that generates a sense signal based on a local voltage level of the supply voltage at the IC, a bias control circuit that adjusts a bias signal based on the sense signal to account for a difference between the nominal voltage level and the local voltage level of the supply voltage, and a signal processing circuit biased by the bias signal.
    Type: Application
