An analog video receiver implemented in an integrated circuit device. The analog video receiver includes a mixing circuit to mix an analog video signal with a sinusoid to generate a frequency-shifted analog video signal, and an offset cancellation circuit to obtain a sample of the frequency-shifted analog video signal during a first time interval and, based on the sample, generate an offset cancellation signal that, when summed with the frequency-shifted analog video signal, reduces a substantially time-invariant offset in the frequency-shifted analog video signal.
