1.51-GHz with Q >10,000 Even in Air!
A result of purposely impedance-mismatching a polydiamond disk with its polysilicon stem.

1.2-GHz with Q = 14,600!

Who says diamond is needed to get Q >10,000 at GHz frequencies? With the right "hollow-disk" ring design, polysilicon can do even better than diamond.

60-MHz Wine-Glass Disk Oscillator Makes the GSM Reference Oscillator Spec!
Higher power handling and a Q >50,000 crucial in making the spec.

Arraying for Impedance <480W at 72MHz!
Mechanically coupled resonator arrays automatically align resonator frequencies to allow output summation for low impedance and higher power handling.

Clark T.-C. Nguyen received the B. S., M. S., and Ph.D. degrees from the University of California at Berkeley in 1989, 1991, and 1994, respectively, all in Electrical Engineering and Computer Sciences. In 1995, he joined the faculty of the University of Michigan , Ann Arbor , where he was a Professor in the Department of Electrical Engineering and Computer Science up until mid-2006. In 2006, he joined the Department of Electrical Engineering and Computer Sciences at the University of California at Berkeley , where he is presently a Professor and a co-Director of the Berkeley Sensor & Actuator Center . His research interests focus upon micro electromechanical systems (MEMS) and include integrated micromechanical signal processors and sensors, merged circuit/micromechanical technologies, RF communication architectures, and integrated circuit design and technology. From 1995 to 1997, he was a member of the National Aeronautics and Space Administration (NASA)’s New Millennium Integrated Product Development Team on Communications, which roadmapped future communications technologies for NASA use into the turn of the century. In 2001, Prof. Nguyen founded Discera, Inc., a company aimed at commercializing communication products based upon MEMS technology, with an initial focus on the very vibrating micromechanical resonators pioneered by his research in past years. He served as Vice President and Chief Technology Officer (CTO) of Discera until mid-2002, at which point he joined the Defense Advanced Research Projects Agency (DARPA) on an IPA, where he served for 3.5 years as the Program Manager of the MEMS, Micro Power Generation (MPG), Chip-Scale Atomic Clock (CSAC), MEMS Exchange (MX), Harsh Environment Robust Micromechanical Technology (HERMIT), Micro Gas Analyzers (MGA), Radio Isotope Micropower Sources (RIMS), RF MEMS Improvement (RFMIP), Navigation-Grade Integrated Micro Gyroscopes (NGIMG), and Micro Cryogenic Coolers (MCC) programs, in the Microsystems Technology Office of DARPA.

Prof. Nguyen received the 1938E Award for Research and Teaching Excellence from the University of Michigan in 1998, an EECS Departmental Achievement Award in 1999, the Ruth and Joel Spira Award for Teaching Excellence in 2000, the University of Michigan’s 2001 Henry Russel Award, and the Cady Award from the 2006 IEEE Frequency Control Symposium. He became an IEEE Fellow in January of 2007. Among his publication accolades are the Jack Raper Award from 2005 IEEE International Solid-State Circuits Conference, the 2004 DARPA Tech Best Technical Presentation Award, the Best Invited Paper Award at the 2004 IEEE Custom Integrated Circuits Conference, and together with his students, the Best Student Paper Award in Category 1 at the 2005 Joint IEEE Frequency Control/Precise Time and Timing Interval (PTTI) Symposium, the Best Student Paper Award in the Frequency Control Category at the 2004 IEEE Ultrasonics, Ferroelectrics, and Frequency Control Symposium, and the Roger A. Haken Best Student Paper Awards at the 1998 and 2003 IEEE International Electron Devices Meetings. To date, he has organized and chaired a total of 35 IEEE and DARPA workshops, and is presently the North American Technical Program Chair of Transducers'07.
