International audience; In this paper, a passive measurement system is used to explore the phase noise of high overtone bulk acoustic wave resonators. The chosen overtone is around 373 MHz and the temperature coefficient of frequency at room temperature is 4 ppm/K. The 1/f noise is clearly shown and a flicker floor of about σy_floor = 1.5×10-11 is demonstrated.
