Hello,
I am trying to use FDC EVM board to measure a capacitor that is part of a larger circuit operating at a higher frequency. I am able to manage filtering so that FDC is not seeing any high frequency noise. However, I see that the FDC values are getting impacted when the parallel capacitors in the larger circuit change. Has anyone tried using FDC for such kind of application?
For example, in circuit below C2 is the capacitor that I need to measure. However, the measured value from FDC is changing when C1 or L1 change. Any suggestions on how to make the FDC in-sensitive to everything else except C2?
