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.
