Patents by Inventor Michael John Mitzen

Michael John Mitzen 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).

  • Analog bias control of RF amplifiers
    Patent number: 11916518
    Abstract: Examples provide methods and apparatus for controlling a DC bias current in an RF amplifier. In one example where the RF amplifier is implemented on an amplifier die, a reference voltage is produced across a reference resistor implemented on the amplifier die, the DC bias current is measured, and a current controller, which is implemented on a controller die that is separate from the amplifier die, operates a feedback loop using the reference voltage to control a level of the DC bias current.
    Type: Grant
    Filed: April 20, 2022
    Date of Patent: February 27, 2024
    Assignee: SKYWORKS SOLUTIONS, INC.
    Inventors: Douglas M. Johnson, Guillaume Alexandre Blin, Michael John Mitzen, Jung Hee Lee, Weize Xu, Attila Kalamar
