Hello everyone,
I want to integrate NFC to one of my projects and I am having a problem with the value of some of the capacitors.
I am looking into using the nRF52832:
I need to figure out the value of the capacitors Ctune1 and Ctune2.
Even though there are equations on how to pick the capacitors, I need some help since this is not my expertise.
I have some questions about this formula.
I am not really sure what is Cp1 and Cp2. Are they related to the antenna? How to determine their value?
Also what is Cint1 and Cint2? Are they Cpad_NFC? if so then it should be 4pF, right?
One more silly question and please forgive the ignorance. For the capacitor and inductor values, what are the units that needs to be used? is it pF, F, uH, H, ...?
It would be really appreciate if you can help me with these questions.
