The transfer characteristics of a noninverting buffer in the ECL family are described by the following equation: 0, V; s 0.85 v V0 = 2.6[ 1 - 1 / { 1 + exp((V, - 1 ) / Vr)}], 0.85 V < V, < 1 .2 V 2.6 V, V; 1 . 2 V Calculate the logic levels and noise margins. Use V7 = 26 mV. Note: Since gain is positive in the transition regions for noninverting circuits, use slope = 1 at logic transition
