I need more data about MEMS and it,s aplication on aeronative.

This is a great article and analysis, but since Mobius Microsystems is mentioned I want to make a clarification. The accuracy of the Mobius all-CMOS frequency generator is significantly better than 0.1%. An article by Dr. Michael S. McCorquodale that will soon be published in JSSC features one of our earlier designs that outperform USB 2.0 requirement with better than 500 ppm (0.05%) accuracy. We are currently making progress in our first frequency generator products with targets for further improvements, so please stay tuned.

Very informative article.

I think you'll find that Rakon is a successful New Zealand company that does excellent work, but is neither located in Japan nor of the scale of the other Japanese producers you mentioned.

There is another MEMS resonator technology out there that would be interesting for you to include: F-BAR or film bulk acoustic resonator. Typically, these are produced on silicon wafers with AlN (a piezoelectric) films to drive the resonator structure.

We are interest of MEMS oscillators
and resonater and with the IC.
