  • Are Sand 9 resonators fundamental or overtone devices?

    November 08, 2013

    Sand 9’s MEMS resonators are fundamental frequency resonators.  Operating at the fundamental frequency simplifies the design of higher frequency oscillators.  Another advantage of Sand 9’s MEMS process is that all frequencies, low and high, are implemented in very small resonator geometries.  The current wafer level package is ¼ the size of the smallest quartz package.

  • What is the possibility of fine tuning the frequency with a voltage? A “VCMO” would be desirable even if the final frequency would require a synthesizer post stage.

    September 13, 2013

    Sand 9’s MEMS technology can be used to make Voltage Controlled MEMS Oscillators (VCMOs). The VCMO would offer several advantages over quartz: e.g., low phase noise, high fundamental frequency, vibration immunity and package integration. The higher fundamental frequency would enable lower noise frequency synthesizers, benefiting performance-demanding applications. The high fundamental frequency is especially useful when […]
