Hi FvM, thx for your answer.
I believe the dissipation is caused by the non-perfect nature of the capacitor :-> the existance of resistive component in the capacitor. and that's what I'm trying to find out here now -> dissipation factor (loss tangent) of the capacitor.
I'd like to have a chip...
Dear Frank,
thx for the reply.
Indeed, in this application an accurate determination of dissipation factor (phase shift between capacitive / resisitive component or current/voltage component) is very crucial, which normally goes down to 0.001, or even 0.0001. I've been using a precision LCR...
I'm looking for a highly accurate phase detector for my capacitive sensing application. In the application, the capacitance is in the range of 1 ~ 10 pF. I've been able to get the capacitance via analog device's AD7745. However, I was requested to have the dissipation factor measured as well...
