i want to know the calculation process of nand , nor 's skew logical effort

Answer 1

#logical effort is the ratio of elp capacitane of a gate to the elp capa ulance of inverter ② delivering same olp current * HE-shewed gates : willing opp by dowonáring Nmos * low-skewed graders billing olp by downsizing pinos Given ALE: No-ecewed inverter Hi-crewed Low-strewed as of high skewed o unshewed with equal gize inverter qu=8 Z 2+1 con olo-skewed with equal fall as other treated C Enverter JI co-skewed inverter unsteurd with equal rise as of co-skewed inverter- CS$canned with CamScanner
