calculate parasitic capacitance Cp of a sensor

Postby larrydahooster » Wed Oct 10, 2012 6:39 am

Hey everybody,

i need to compare and evaluate sensors of different size and shape. So i decided to use the parasitic capacitance Cp as measure for evaluating.

Now to the Problem. I found an equtation in an outdated applicationnote from 2008,

but this does not work, becuase i am using IDAC Source with psoc5.

I know that raw count is a value based on Cp, but how do i calculate it the Cp from it?

If you cant help me with Cp, maybe you experienced other ways to compare and evaluate Sensors.
Any help is welcome, larrydahooster
