Print Noise Summary. What is the noise unit for currents?

Hello everybody,

I am comparing my noise simulations with the calculations.

If I print the noise summary (spot noise), I can select either V^2 or V.

By selecting V^2, at the end of the printed list there is this sentence:

"Spot noise Summary (in V^2/Hz)..."

However, in the printed list there are current noise densities as well (id, igs, igd, igb).

For example, i get

id    4.60029e-15

What is the unit for these current densities? Should I interpret it as  A^2/Hz? Or is it multiplied by something to get the unit V^2/Hz? 

Thanks!
