for nmos transistor
the on resistance Ron is given by the equation
Rtransistor =Lg0/(Width* mu *COX*(VDD-VT0))
i use the following values
Lg0 17.5 nm -> .0175 micro meter
width 140 micro meter
this make w/l =8000 which i think very reasonable
VDD 1 volt
VT0 0.18 volt
from my model i found COX 3.137727e-14 farad per Micro meter ^2 which i think reasonable
i use the mobility of electron mu 1500e8
these all give me Ron=.32 ohm
i think Ron is in the range of hundreds of ohms, i found this in literature
so i do not know what is wrong with my calculation
what do u think?
