i have NMOSOP5 in pspice

its specification is

* Level-1 Model for NMOS in model 0.5um CMOS Technology
* (created by Anas Hamoui & Olivier Trescases)
.model NMOS0P5 NMOS(Level=1 VTO=0.7 GAMMA=0.5 PHI=0.8
+ LD=0.08E-06 WD=0 UO=460 LAMBDA=0.001 TOX=9.5E-9 PB=0.9 CJ=0.57E-3
+ CJSW=120E-12 MJ=0.5 MJSW=0.4 CGDO=0.4E-9 JS=10E-9 CGBO=0.38E-9
+ CGSO=0.4E-9)

Simulate the circuit and use a slow ramp voltage for Vdd (you can do the with a pulse voltage source and setting a slow rise-time, say 1 ms).
At the point Id1 = 10mA, measure Vgs.
