BPN540: Temperature-Stable Micromechanical Resonators and Filters

Alper Ozgurluk
2017

This project aims to suppress temperature-induced frequency shift in high frequency micromechanical resonators targeted for channel-select filter and oscillator applications. A novel electrical stiffness design technique is utilized to compensate for thermal drift, in which a temperature-dependent electrical stiffness counteracts the resonator’s intrinsic dependence on temperature caused mainly by Young’s modulus temperature dependence.

BPN701: Bridged Micromechanical Filters

Jalal Naghsh Nilchi
2017

The overall project aims to explore the use of bridging between non-adjacent resonators to generate loss poles in the filter response toward better filter shape factor, sharper passband- to-stopband roll-off and better stopband rejection.

Toward A Levitated Micromechanical Resonator

Ilya Gurin

Liwei Lin
2010

Capacitive micromechanical (MEMS) resonators promise to dramatically improve the design of RF front-ends for wireless communications by virtue of their high quality factor (Q). Unfortunately, the physical limitations of MEMS resonators’ Q are poorly understood, and the highest Qs have proven difficult to achieve reliably. In order to...

Integrated MEMS Cavity Optomechanical Oscillators for Wireless and Optical Communications

Turker Beyazoglu

Ming C. Wu
Liwei Lin
2016
Recent advancements in micro-optical and micro-mechanical resonator technologies haveallowed researchers to exploit coupling between the optical field and mechanical motionin an optical cavity to affect cooling or amplification of mechanical motion. Cooling the mechanical motion of microscale objects has been of high scientific interest, since it facilitates observation and exploration of certain quantum phenomena, e.g., the standard quantum limit of detection. On the other hand, amplification of the mechanical motion...

Non-Linear Stiffness Extraction and Modeling of Wineglass Disk Resonators

Alain Anton
Clark T.-C. Nguyen
2018

Over the past three to four decades the popularity of MEMS has continually grown with the development of different technologies ranging from thin film bulk acoustic resonators (FBAR), to capacitive gap transducers, and surface acoustic wave (SAW) resonators, just to name a few. Each of which has their own benefits and drawbacks when considering different applications, say sensors or radio frequency (RF) front end components. For example, the prevalent use of FBAR in consumer electronics for RF wideband filters is largely due to the technology’s ability to suppress spurious modes,...

Hollow Disk Electromechanical Coupling Cx/Co Boosting

Yafei Li
Clark T.-C. Nguyen
2018

The growing need for high performance but low power microelectromechanical system (MEMS) devices capable of operating at various frequency regimes, including high frequency (HF), very high frequency (VHF) and ultra-high frequency (UHF), fuels an increasing demand for resonators with simultaneous high quality factor (Q) and high electromechanical coupling, as gauged by the motional-to-static capacitive ratio (Cx/Co). Capacitive-gap transduced resonators have already posted some of the highest disk Cx/Co-Q products to date at HF and low-VHF. Attaining similar performance at the high-VHF and...
