Lin:

1. look up " chapter 4, Capacitor sensors in Vol. 7, Mechanical Sensors" of
the Series "Sensors--a Comprehensive Survey" published by VCH in Germany,

2. Check with Ms. Huang,Guojeng of your University, Electronics Department,
under Prof. C hang, Guo-ming.  The CP-10 circuit can be usaed ---But it is
patented circuit.

Hello,
>        Recently,we will design an accelerometer.In our opinion , we
>    want to use the method of "capacitive detection" to sense its
>    G value. Does anyone know that if we want to sense the value correctly,
>    how about the range of capactiance value?
>    About pF(10^-12) or fF(10^-15) or others.
