Q-factor of the LC tank from being decreased dramatically for this period. However, Q CPL serves as a current source in the proposed VCO. Although Q CPL in the triode region is not a good current source, the phase noise is improved due to the absence of noise from a current source. The QVCO without

## Abstract This paper reports an efficient method to measure the phase noise of free‐running microwave voltage‐controlled oscillators using a general‐purpose spectrum analyzer. The system tracks the frequency drifting signal by using a charge pump phase‐locked loop. The measurements taken on a 1.9
