The transfer characteristics of a noninverting buffer in the ecl family are described by the following equatio:

0, v s 0.85 v v, 2.601 1/11 exp((v 1)/vd)], 0.85 v s vi s 1.2v 2.6v vi e 1.2 v

calculate the logic leveles and noise margins (vol, vol(max), voh, voh(min), vil, vih, nml, nmh). use vt = 26mv.

note: since gain is positive in the transition regions for noninverting circuits, use slope = 1 at logic transitions.
