A question that is about the bias of a NMOS transistor

Hello everybody,

I have a question that is about the bias of a NMOS transistor described in next line.
Why does the drain-source voltage become larger if chosen to the longer gate lengths ?

 

[shweta_eda]

on comparing mosfet lenghthwise, it acts as a voltage divider. so as the length increases voltage also increases. Thats why vds increases with L.

Question isn't correct. What is the testing circuit?

Because the gm of the transistor decreases ;-)
