NFC CLRC 6630 IC RX sensitivity adjustment

[20140805066]

Hi, i made an NFC Antenna design and tuning circuit based on the CLRC6630 IC and the Antenna Design Tool provided by you guys, but the one thing i could not understand is how do i determine the values of the components connected to the two Rx pins depending on my antenna values,i hope that you can explain the logic behind determining the values  point me in the right direction, i am providing a picture of my values of the antenna and tuning circuit design, thank you in advance.

Hello Mohammed,

The antenna design tool provides the calculations for the matching circuitry. Essentially this is to help jump start the antenna matching and tuning. Which consequently as you mentioned it provides the Tx values.

For the Rx side of the design you can follow the guide and recommendations provided in the CLRC663 Antenna Design, starting in section 4.4. Here you will find the recommendations and step-by-step guide of how to optimize the receiving side an what adjustments you can being to make in order to get the best results you can.

Let me know if the above information is useful, or if you have any additional questions.

Have a great day!
