Abstract
In one embodiment a tracking circuit for tracking a frequency of a sweeping signal component in an input signal comprises an input for receiving the input signal (Sin) comprising the sweeping signal component and a noise component, a mixer coupled to the input and configured to mix the input signal with a replica signal and therefrom provide a residual input signal, a low-pass filter coupled downstream of the mixer, a discriminator circuit coupled downstream of the low-pass filter, a loop filter coupled downstream of the discriminator circuit and configured to provide a frequency control value, and a replica signal generator circuit coupled downstream of the loop filter and configured to provide the replica signal with a frequency adjusted based on the frequency control value, wherein the frequency of the replica signal represents an estimation of a frequency of the sweeping signal component propagated to a current time unit of the input signal.
