I have a sensor that can be modeled as a capacitor and resistor in series. The problem with this resistor is the resistance is on the order of 10's MOhm and the capacitance (we believe) is single pFs.
I have tried using a resonant circuit to find the capacitance, but the results end up super noisy and with an extremely low q factor. Does anybody have any ideas of how to determine the capacitance?
