The Q factor determines how accurately you can measure the resonance frequency.
High Q factor means high accuracy. This is very important for resonant sensors.

For filter applications The Q factor determines the bandwidth.

        Emne: [mems-talk] High Q resonator



        Dear all,

        One of the hot topics in RFMEMS is high frquency high Q rsonator. It
seems
        that a high Q is of critical importance for MEMS resonators.

        However, i did not see any literature that specifies why a high Q is so
        important. Could anyone tell me why we need a such high Q? (I would likt
it
        to be mathematical)

        Thank you very much!

        Yanni
