Systems and methods for suppressing oscillator-induced spurs in frequency synthesizers

An electronic device, comprising:

• a first oscillator configured to output a first clock signal,
• a second oscillator that is co-located with the first oscillator on the electronic device,
• wherein the second oscillator is configured to output a second clock signal,
• wherein the first clock signal exhibits a first signal spur caused by the second oscillator or by the second clock signal;
• a first bandpass filter configured to filter a first input signal derived from the first clock signal received through a negative feedback loop, and to output a first signal component corresponding to the first signal spur;
• and
• a signal reconstruction circuit configured to receive the first signal component and to combine the first signal component into a control signal for the first oscillator, and to feed the control signal combined with the first signal component to the first oscillator to mitigate the first signal spur exhibited in the first clock signal.
