Claim 14:
15. The electronic device of claim 14, wherein the dithering circuit includes:
a divider configured to divide a free-running frequency of the voltage controlled oscillator to generate a dithering signal;
an alternating current (AC)-coupling circuit configured to AC-couple the dithering signal;
a first switch connected to the AC-coupling circuit and configured to pass the dithering signal in the first phase according to the FSM;
a direct current (DC)-coupling circuit connected to the first switch to DC-couple a temperature proportional voltage proportional to an absolute temperature of the voltage controlled oscillator, and bias the dithering signal to the temperature proportional voltage; and
a second switch connected to the AC-coupling circuit and the DC-coupling circuit and configured to pass the dithering signal biased to the temperature proportional voltage in the first and second phases according to the FSM.
