Hi :
In TIDA-060029 Section 3.2.2, Is the value of Rf/Zx calculated from Vin/Vout? How is the phase calculated? Is there a detailed calculation process?

Hello Jochen,
We are releasing an updated high frequency version of the LCR reference design soon which will cover more details on how phase is calculated. You are correct, the value of Zx is calculated by measuring Vin, Vout, as well as knowing and measuring the value of Rf via calibration. The phase is calculated via the time delay between Vin and Vout.
I sent you a friend request. Once the request is accepted, I can share parts of the updated reference design with you which goes into more details.
Thank you,
Sima
Hi Sima:
I'm very glad to get your reply. And I'm looking forward to seeing TI's latest design, which will be of great help to me.
Best regards,
Jochen
Hi Sima:
I have accepted your friend request, can you share the latest version of the LCR reference design with me? Thanks a lot.

Hello Jochen,
I shared the file it in private messaging; please let me know if you have additional questions on the method.
Thank you!
