abstract = "This paper describes the oscillator based on High-overtone Bulk Acoustic Resonator (HBAR) at 3.7 GHz for Chip Scale Atomic Clock (CSAC) application. The HBAR is built on a 400μm thick sapphire with Al/ZnO/Al sandwich layers having thicknesses 0.1μm/0.8μm/0.-1μm, which ensures the best acoustic coupling and highest Q (above 19,000) at around 3.7GHz. The oscillators have been designed, fabricated and measured to have very low phase noise and low power consumption. The oscillator when measured with Agilent 4448 spectrum analyzer is measured to oscillate at 3.677 GHz with output signal power of -15dBm and phase noise of -108 dBc/Hz at 10kHz offset and -125dBc/Hz @100kHz offset, respectively, while consuming only 6.21 mW.",
