Integrated circuit with calibrated pulling effect correction

A frequency-control circuit for reducing interference from a pulling signal having one or more unwanted frequency components, the frequency-control circuit comprising:

• a phase frequency detector (PFD) configured to receive a reference frequency signal and generate an output detection signal;
• a loop filter coupled to the output of the PFD, the loop filter configured to filter the output detection signal and generate a control voltage signal;
• a voltage-controlled oscillator (VCO) coupled to an output of the loop filter, the VCO configured to receive the control voltage signal and generate an output frequency signal;
• and
• a frequency divider coupled to an output of the VCO and an input of the PFD, the frequency divider configured to receive a baseband signal that is a function of the pulling signal and output a correction voltage that corrects for the one or more unwanted frequency components of the pulling signal,
• wherein the PFD is configured to detect a difference in phase and frequency between the reference frequency signal and a feedback of the output frequency signal including the correction voltage,
• wherein the output frequency signal from the VCO has a reduced number of the one or more unwanted frequency components of the pulling signal.
