Several times I get this indication from datasheets:
but it's not the common case.
Normally I get nV/√Hz (noise density in the bandwidth range).
And when I need to compare 2 or more devices, if some of them has the NF in dB, I can't. It is like to compare apples with oranges.
The dB value is referred to what? Since dBs in voltages are always 20 times logarhythms of ratios.
The goal i to convert form one format to another, to be possible to compare stuff.
