Cutoff Region
The voltmeter voltage is controlled by the independent voltage source.
More precisely Vgs < Vth.
Vth = VTO = 3V
K = 1 mAV^-2
Vgs = Vg - Vs
= 1V - 0V
= 1V (<3V)
Id = 0A
That's it, 10V input (independent voltage source) = 10V output (voltmeter) with Id = 0A.
Notice:
1. Width = 90 nm
2. Length = 119 nm
3. KP = 1 mA/V^2
4. VTO = 3V
5. Lambda = 200 m1/V
