Having now produced devices with sufficient Q, thermal stability, aging stability, and manufacturability, vibrating RF MEMS technology is already finding its way into next generation timing and wireless applications. At this juncture, the technology is now poised to take its next logical steps: higher levels of circuit complexity and integration. In particular, as vibrating RF MEMS devices are ...

MEMS Oscillator design for high frequency application is approached in this project and its gain, noise and power are analyzed. The CMOS Micro Electro Mechanical System resonator structure is modeled using its RLC equivalent circuit where all passive components are extracted by COMSOL Mutiphysics tool. MEMS based oscillator requires to be combined with amplifier circuits to improve the performa...

This paper is the 3rd in a series of papers discussing characterization of a Micro-Electrical-Mechanical-System (MEMS) deformable mirror in adaptive optics. Here we present a comparison between a conventional adaptive optics system using a Xinetics continuous face sheet deformable mirror with that of segmented MEMS deformable mirror. We intentionally designed the optical layout to mimic that of...

Wireless MEMS sensors network has been widely used in many fields. In this paper the MEMS pressure sensor is integrated on a sensor board with Zigbee sensor network for real-time local bridge scour depth monitoring during a flood. The wireless MEMS pressure sensor scour monitoring system has been developed and tested in the laboratory. Local scour is one of the major factors for bridge failure....

We have proposed a unified approach to the modeling and study of developments in the field of MEMS and Nanotechnology and its application in futuristic Nano-enabled Cells. We have proposed a novel to approach reliability of MEMS enabled fuel cells. We know that reliability and accurate prediction of properties in nano domains remains a major challenge where still theories are being developed to...

CMOS micromachining processes are being increasingly used to fabricate integrated MEMS devices. Verification of such designs requires extraction from layout to mixed domain circuits and MEMS schematics for lumped parameter simulation. The higher etch hole density and multilayer interconnect in CMOS-MEMS designs results in a larger and more complex problem than in polysilicon MEMS. In addition, ...

The package and interconnection are critical concerns that influence the reliability of MEMS sensors applied in modern automotive under random vibration conditions. This paper conducts a research on this problem to reveal the reliability and influencing factors of MEMS on board level using finite element modelling and random vibration response simulation method. The ADXL78 MEMS chip is used as ...

Integrated GPS/INS systems provide an enhanced navigation system that has superior performance in comparison with either system operating in stand-alone mode as it can overcome each of their limitations. The high cost and government regulations prevent the wider inclusion of high quality IMUs to augment GPS as a commercialized navigation system in many navigation applications. The progress in M...
