I have a micro capacitor sensor with C0 around 10pF, it changes +- 4pF (so I am in the range of 6 to 14 pF).
I am currently using a laboratory wire conditioning preamplifier (charge preamplifier Bruel&kajer 2626) with a sensitivity of 1V/pCoulomb
to convert the charge across the micro capacitor sensor to voltage and them I process this voltage by my data acquisition system.
I am looking for:
1- a chip to convert the charge ( or capacitance) to voltage instead of the laboratory conditioning preamplifier,
2- A method to measure this voltage wireless in order to process it using my data acquisition system.
Could I find my request here?
Please feel free to ask me any question to clarify,
