Hi, I'm into chracterizing i/o cells. I want to know how to measure DC specs like Vih,Vil,Voh,Vol. Suppose, I f I know worst case Ioh or Iol then, can I load the o/p of the cell with that current, and see how much is the voltage available at that load and treat it as Voh/Vol. But as per Jan Rabaey book (dig. Int. circuits) I could see, its proposed to use the DC trans. curves and the voltage corresponding to unity slope in curve is assumed to be Voh/l. Could anyone clarify on this.
