[krishmaniac]

Appreciate if anyone can give me expression for MOSFET rise and fall times. Any links or explanation is very much apprecicated. Thanks.

good day
i build a d.c.i. for 3 and 5 level and i used mosfet and got the results for v and i for different loads and now i am trying to apply a vpulse on pspice on these ccts but i am failing, i think i dont know where to apply this modulation and wheather the parameters are right or wrong , u know i should input the v1 and v2 and td and tr and tf and pw and period....any one could please guide me....thnx alot

i do aplogize that i was really new here in this site... and for what i need i was asking about the parameters of the vpulse in pspice that needed to be applied as modulator in the 3-level diode clamped inverter...i did build the 3-level d.c.i. but when applying the vpulse on some switches things going not logic results and really crazy...i am in need for the parameters of vpulse and the location of modulator(vpulse)...thanks alot in advance and i am sorry again to interrupt your post...
