i need help help to find the find Uncox through cadence
model file contain these value i nedd Uncox
model nch atft
+type = n
+wd = 0 ld = 0 ldif = 0
+acm = 1 level = 35
+tox = 2.5e-08 tnom = 25
+vto = vth0+vthl/(l*1e6)
+cgso = 7.66e-10 cgdo = 7.66e-10 alphasat = as0+asl*l
+def0 = 0.361414 delta = 1.99262 el = 1.07462
+emu = 0.71204 eps = 2.9 epsi = 7.62
+gamma = 0.751591 gmin = 3.84507e+25 iol = 9.9998e-21
+kasat = 0 kvt = 0 lambda = 0.0154733

+rsc = rcr/w rdc = rcr/w vmin = 0.0178933

ends nch
 

If you know gate oxide material then tox with eSi*e0 gives you Cox.
I see nothing for mobility or k' so maybe it's defaulted.

You could always set up a simulation and extract k' by the device
equation in saturation region. Two Id/Gv points, do the math.
