Systems and methods for controlling frequency synthesis

A wireless device comprising:

• an antenna configured to facilitate reception of a radio-frequency (RF) signal;
• a receiver in communication with the antenna, the receiver configured to process the RF signal;
• and
• a frequency synthesizer in communication with the receiver, the frequency synthesizer circuit including a control system, the control system including a phase detector configured to receive a reference signal and a feedback signal, the phase detector further configured to generate a first signal representative of a phase difference between the reference signal and the feedback signal, the control system further including a charge pump in communication with the phase detector, the charge pump configured to generate a compensation signal based at least in part on the first signal, the control system further including an oscillator in communication with the charge pump, the oscillator configured to generate an output signal based on the compensation signal, the compensation signal configured to reduce or substantially eliminate one or more spurs associated with the frequency synthesizer.
