  • RF variable gain amplifier
    Patent number: 7633342
    Abstract: A RF variable gain amplifier with an extended linear tuning range is disclosed. The variable gain amplifier employs a wide swing cascode mirror formed by two cascode transistors and two gain transistors. The two cascode transistors track each others so are the two gain transistor. The gain transistors operate on the saturation region.
    Type: Grant
    Filed: September 17, 2008
    Date of Patent: December 15, 2009
    Assignee: VIA Technologies Inc.
