Abstract
A circuit includes an interference frequency tracking circuit, a PLI synthesizer circuit, and a summing circuit. The interference frequency tracking circuit is configured to track a frequency of an interference signal derived from a target signal, and provide a frequency selection value representing the frequency of the interference signal. The PLI synthesizer circuit is configured to generate, based on the frequency selection value, a correction signal at the frequency of the interference signal, adjust a phase of the correction signal to match a phase of the interference signal in the target signal, and adjust an amplitude of the correction signal to match an amplitude of the interference signal in the target signal. The summing circuit is configured to subtract the correction signal from the target signal.
