BPN972: Temperature-Insensitive Resonant Strain Sensor

Xintian Liu
Kevin H. Zheng
2024

Explore the ultimate capability of a vibrating ring-based electrical stiffness-based resonant strain sensor, rigorously confirming a superior insensitivity to temperature that should permit it to operate under wide temperature excursions, such as experienced in harsh automotive environments.

BPN953: Long-Term Drift of MEMS-Based Oscillators

Xintian Liu
Kevin H. Zheng
2024

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.

BPN976: Fully-Integrated MEMS-Based Wireless Receiver

Kevin H. Zheng
Qiutong Jin
Xintian Liu
2024

Recent MEMS process advancements from our group have enabled a class of low-temperature, thin-film ruthenium RF filters that can be processed directly on top of CMOS wafers. This work seeks to demonstrate the first low-IF receiver with fully-integrated MEMS-based RF channel-select filters, which permits low power applications in high-sensitivity, narrow-band software-defined communications and cognitive radio.

BPN828: Zero Quiescent Power Micromechanical Receiver

Qiutong Jin
Kevin H. Zheng
2024

This project aims to explore and demonstrate a mostly mechanical receiver capable of listening signals within low-frequency and very-low-frequency range. The receiver is designed to consume zero power at standby and consume very litter power (nW) only when receiving valid bits.
