It will be shown that both oscillators and phase-locked loops display an upper bound in their efficiency that is fundamentally thermodynamic limited. Such upper bound will be used to derive two comparative figure-of-merits (FoMs) that resemble the one already present in literature. Finally, an analysis of the state of the art of the designs already present in literature confirms the proposed analysis. Keyphrases: Figure of merit (FOM), Jitter, Phase Locked Loop (PLL), Voltage Controlled Oscillator (VCO), phase noise, time domain
