  • Low noise oscillators
    Patent number: 8451071
    Abstract: An oscillator having: (A) a transistor for producing an oscillating output signal at an output electrode of the transistor. The oscillator includes; (B) a bias circuit for producing a bias signal for the transistor, said bias circuit including an amplifier coupled to the output electrode of the transistor; and (C) a circuit coupled between an output of the amplifier and a control electrode of the transistor, for isolating the bias signal provided by the amplifier from the oscillating signal.
    Type: Grant
    Filed: April 18, 2011
    Date of Patent: May 28, 2013
    Assignee: Raytheon Company
    Inventors: Roger L. Clark, Mark J. Gugliuzza, Benjamin J. Annino, Janis R. Cooper
