    How to calculate the absolute capacitance value?

      Hi, I have two questions on my project.

         

      1. how to calculate the absolute value of capacitance according to the raw data? Is there a equation to do this?
      Since the resolution is 0.1pF, i assume the detection range is 0 to 25.5pF? Is that correct?

         


      2. For the sensor we are going to use, 100kHz will be a proper frequency for the stimulation signal. So, how to set the stimulation signal frequency or can we use external signal source to drive the sensor? What is the  frequency range it support?

      Thanks for any answers!
