To reduce the phase noise of MMIC phase-locked oscillators (PLOs), we study the phase noise properties of PLOs given that the oscillator Q factor is relatively low in monolithic circuits. Such PLOs must have wide bandwidth in order to suppress monolithic oscillator noise. Therefore, to reduce MMIC PLO phase noise, the phase noise in the PLO passband has to be decreased. Noise generation by each component of the PLO, and its contribution to the output are discussed with emphases on experimental estimation and rigorous analysis of the component phase-or baseband-noise. Based on these results, a new loop configuration is proposed for reducing phase noise in the PLO using a low Q-factor oscillator. It is demonstrated experimentally that PLOs based on the new loop exhibit dB lower phase noise than conventional PLOs.
