Patents by Inventor Pavel Bretchko

Pavel Bretchko 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 amplifiers
    Patent number: 7750734
    Abstract: Circuits and methods for reducing distortion in an amplified signal are disclosed. The circuits and methods may use multiple single-ended gain stages to produce multiple amplified signals. The amplified signals may be processed in combination to produce a resulting output signal having little, or no, distortion. The circuits may be implemented on a single chip as integrated circuits.
    Type: Grant
    Filed: March 21, 2008
    Date of Patent: July 6, 2010
    Assignee: Analog Devices, Inc.
    Inventors: Pavel Bretchko, Shuyun Zhang, Royal Gosser
  • HYBRID IMPEDANCE MATCHING
    Publication number: 20100019857
    Abstract: Impedance matching techniques can be used to match an amplifier to an antenna for signal transmission. Some impedance matching techniques use an integrated passive component and an integrated transformer. Some impedance matching techniques include the use of an integrated n:m transformer, where n?m. Several n:m transformer implementations are described.
    Type: Application
