Hi Win,

I can't seem to find where I stashed your gate-charge subcircuit. (*)

Pointer or re-post?

Thanks!

(*) I have a PhD that needs an education ;-)

Give me more of a hint, doesn't ring a bell.
Are you talking about subthreshold MOSFET
modeling?

Maybe I remembered wrong. I thought you had developed a gate-charge
subcircuit add-on. I have a situation where I need to model fast
turn-on and turn-off of an FQN1N60C.

Solved....

Rather elegantly, maybe up to paper submission quality ;-)

I need to add some more parameterization to make it easer to set the
breakpoints and then I'll publish how I did it.

(No voltage-controlled switching like in some papers I've found...
note the smooth curves ;-)
