Yang Edward Li 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).

  • Stacked linear power amplifier with capacitor feedback and resistor isolation
    Patent number: 8487706
    Abstract: A power amplifier with stacked, serially connected, field effect transistors is described. DC control voltage inputs are fed to the gates of each transistor. Capacitors are coupled to the transistors. The inputs and the capacitors are controlled to minimize generation of non-linearities of each field effect transistor and/or to maximize cancellation of distortions between the field effect transistors of the power amplifier in order to improve linearity of the power amplifier output.
    Type: Grant
    Filed: January 25, 2010
    Date of Patent: July 16, 2013
    Assignee: Peregrine Semiconductor Corporation
    Inventors: Yang Edward Li, Robert Broughton, Peter Bacon, James Bonkowski
