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. Thank you very much!!!! sincerely, ------------ Yu-Chern Lin Electrical and Control Eng. National Chiao-Tung University,Taiwan E-Mail:u8612519@cc.nctu.edu.tw
