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.
