Abstract

An analog video receiver implemented in an integrated circuit device. The analog video receiver includes an amplifier to amplify an analog video signal having a desired carrier frequency, and a mixing circuit to mix the amplified analog video signal with a complex sinusoid having a frequency substantially equal to the carrier frequency.
