  • Video receiver with adaptive image rejection
    Patent number: 7542100
    Abstract: An analog video receiver implemented in an integrated circuit device. The analog video receiver includes first and second mixing circuits to generate a complex baseband signal by mixing a carrier-frequency analog video signal with respective sinusoids of a quadrature sinusoid pair; and a filtering circuit to subtract a scaled complex conjugate of the complex baseband signal from the complex baseband signal.

  • Synchronously coupled oscillator
    Patent number: 7005930
    Abstract: A phase synchronous multiple LC tank oscillator includes a plurality of oscillator stages that are configured to oscillate synchronously. The phase of each of the plurality of oscillator stages is substantially the same and the plurality of oscillators are inductively coupled. The synchronous oscillation is substantially caused by magnetic coupling. The oscillator stages may be electrically coupled during a first time period and the electrical coupling and disconnected or reduced during a second time period.
