Hello,
I have, what may be, a dumb question.? I have been attempting to Monte Carlo some of the BJT parameters on the 2N3904, NPN transistor.? Some of the directives I have tried include (as an example of the bf parameter):
.model 2N3904 NPN(bf=300)
.param bf={mc(300, tol)}
.param tol=0.5
.step param x 1 100 1
and so on.
Other parameters I would be interested in mc'ing are: Vaf, Var, Rb, Xtb and Trb1.? I have been having no luck and was wondering if it is even possible to do an mc on the parameters of a standard bjt library compopnent.? Do I need to make my own sub circuit?
Please let me know.? Thanks AH
