Reliability • KPOH = Power-On hours for MTBF (thousand) • Vmax = Max permitted gate-dielectric voltage without overshoot • Vos = Maximum permitted overshoot voltage when used with a maximum dc level of Vh < Vmax
Reliability for NFET • Temperature = 25ºC • Switching Probability to Vh = 50% • Tos = 50% of a switching cycle • Device Length = 50nm • Temperature = 75ºC • Vmax • Inversely proportional to KPOH • Inversely proportional to log of Device Size
