Claim 4:
5. The oscillator of claim 4, wherein the dithering circuit includes:
a divider configured to divide a free-running frequency of the voltage controlled oscillator to generate a dithering signal having a specific frequency width;
an alternating current (AC)-coupling circuit configured to AC-couple the dithering signal;
a first switch connected to the AC-coupling circuit to pass the dithering signal according to a switching operation;
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 to pass the dithering signal biased to the temperature proportional voltage according to a switching operation.
