Mahmoud Mohamed Rashad Ibrahim Elhebeary 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).

  • Flip voltage follower low dropout regulator
    Patent number: 10429868
    Abstract: A wide-tuning range low output impedance flip voltage follower (FVF) low dropout regulator (LDO) for large capacitor switching loads is disclosed. In some implementations, a touch sensing controller driver includes the LDO, which has an operational amplifier and a FVF. The FVF can have a gain device, a source follower device, and an adaptive level shifter coupled between a drain of the source follower device and a gate of the gain device.
    Type: Grant
    Filed: October 29, 2018
    Date of Patent: October 1, 2019
    Assignee: QUALCOMM Incorporated
    Inventors: Mahmoud Mohamed Rashad Ibrahim Elhebeary, Sameer Wadhwa
