[quote author=Ken Kundert link=1130856611/0#1 date=1131143846]Why do you believe that the units for var(n) are A2/s? I expect the units to be A2, in which case the units work out properly for the equation given in the paper.

Basically, var(n)=rms(n), if it is root mean square, it should be averaged over time.
also from wiener-Khinchine theorem, what we get from integrate(sphi(f)*df) is total power, should have units of A^2/s.
Only if we have different difinition on var(n)?
