sensitivity units

I am working on FM receiver IC and I have some questions about sensitivity
I saw different datasheets and they mentioned differently in sensitivity.

Basically, I can see several of them in the following
(1) dbm
(2) dbuVEMF
(3) uVEMF

Can anyone tell me what is uVEMF and how can I convert it back to dBm as I need this value to calculate the system NF

units of sensitivity

Here I am trying to answer my question after detailed searching

V emf is the RF input voltage where it's referred to open terminal. I got the answer from a book " Secrets of RF circuit design". To be honest, only this book I can search to explain clearly the meaning of V emf

I think, you'll find an explanation in any profound RF text book. But one correct explanation should be sufficiant for the time being.
 

units os sencitivity

For FM receivers, the sensivity is measured as dBm for a certain SNR at the output.For instance, it's said -80dBm for 14dB SND etc.
