I want to know a measurement circuit at the 1khz of Voltage Noise Density.
for 2.9nV/rtHz (f=1Khz)
Because I cannot measure 1Khz by a measurement circuit of figure 2
Thanks

Hello Masataka,
See Art Kay's Noise articles:

Nose measurement is not easy, and instead of re-explaining here, please see the articles.
As for the LMP7731, it was measured in a gain of 1000 (10ohm/10kohm).
Regards,
