Abstract :
This document presents the results of investigation on a particular stress-compensated SAW resonator configuration allowing a strong improvement in g-sensitivity performance while keeping ultra-low noise characteristics. A specific oscillator architecture integrating two of these resonators is then described and tested. The final result is a 1GHz oscillator presenting unprecedented performances in g-sensitivity (<;2.10-10/g in all axis) and phase noise (-154dBc/Hz at 3kHz offset, -175dBc/Hz noise floor).
