This is definitely a case where the series model is the appropriate
solution.

Subject: [IBIS] [IBIS-Users] pass-trans curves



Hi  IBIS  expert,

I have to modelling a multiplexer with only
one input D  and two  output S1, S2.
the equivalent circuit is in the attachments.
( note that between  D and S1 there is no buffer
  structure , but only  a pass-transistor, the same
  between D and S2 ).

I have characterized  EN,  D , S1 , S2 as input model type
(only clamp curves) and  S1  S2  are characterized
through  [series Mosfet].
Is this a correct and complete characterization ?

if  you think that S1 and S2 have to been associate to
output model type, in which way I can extract pullup
, pulldown , rising , falling curves, if I haven't got a typical
cmos structure as in this case?

I hope that my exposition is clear!

thanks,
Fabio
