Hi Marco,

I summed  E = SUM(V(t) x I(t))dt as you did too and got this:

From my little test:

Not sure what it means but maybe the drop in your energy at the end 
is some oscillations or something to do with a lower band width.  In 
my high bandwidth case, I get a lot of ripple, but the power ends up 
the same at the end as the first peak.

Cheers,

        Terry
