Hi Team
We are working on NFC for our new product.
When we measure the power level each GPIO we don't reach more than 700mv.
Changing the antenna to a larger antenna did not increase the power level
My question is why we don't see any change in the power level if we change the antenna to a bigger antenna
Hi
Thank you for the answer
This is the design:.
According to the datasheet and the NFC document
NFC VOLTAGE should be 1v or VCC*0.4
The reason I ask this is that we want to be sure the design is good,and that NFC will work in the best way
We changed the capacitor to 120pf when we using 2uH,But still dont see the voltage more than 650-700 mv
Hi,
not sure what NFC voltage you are refereeing to, Vsense in our PS?
Your goal by trying to measure the voltage, is it to tune the antenna?
Best regards,
Kaja
