Measurement of iNn
To measure the negative input current noise iNn, we set R3=0 and use
the gain must be lower in order to decrease the thermal noise contribution:

Measurement of iNp
To extract iNp from
value of R3 must be chosen in order to keep its thermal noise contribution as low as
possible against the iNp contribution.
