early voltage mosfet

I wanted to know which is the parameter which pertains to the early voltage of the mos.
 

mosfet early voltage

Early voltage of mosfet is given by
V=Mod(Ids)/gds
Ids= Drain current
gds= small signal output conductance =1/rds
rds= small signal o/p resistance
 

early voltage in mosfet

thank you for the info...
but my question was whether we can get the early voltage of the mosfet through some parameter in the device model...
 

mosfet gds

how about trying lambda in the model?
 

early voltage mos

Nothing in the model file would give you that information.
You need to calculate it graphically. Or Can take help of one of the appendix from Allen holberg.
 

early voltage fet

Well... ya... that was precisely my doubt... I could not find any parameter in the model which would lead me to find the early voltage.
Well thanks anyway to all the guys who replied... there are various indirect ways of finding it out.. But just wanted the fastest method (which couldnt have been a simpler than a small computation from the model)...

Vearly=1/LAMBDA~ L/Ids
