Abstract
A spur cancellation circuit receives a target spur frequency indicative of a frequency of a spur to be canceled and supplies a spur cancellation signal based on the frequency. A frequency tracking circuit tracks a change in the frequency of the spur to be canceled based on a change in phase of the spur cancellation signal and generates an updated target spur frequency based on the change in the frequency of the spur.
