BPN953: Long-Term Drift of MEMS-Based Oscillators

Abstract: 

This project seeks to characterize and de-mystify mechanisms behind long-term drift in MEMS-based oscillators, including ones employing various sustaining amplifiers and referenced to resonators constructed in a variety of materials, including silicon, polysilicon, AlN, diamond, and ruthenium. A measurement apparatus that suppresses unwanted sources of drift, e.g., temperature, to better focus on resonator and oscillator long-term drift will be instrumental to success and will likely entail the use of double or triple ovens, as well as environment resistant circuit design.
