Let’s fix the values found and then look at the datasheet chart that shows output conductance gos as a function of drain current Id:
and let’s report pairs of derived values in the second table in order to extract LAMBDA value:
Get the value of LAMBDA, fix it and proceed with the next graph. It’s the case of a curve showing the evolution of drain current Id as a function of the voltage Vgs between gate and source:
Insert the pair of values in the third table available on PSpice Model Editor and interpolate the curve:
that allows us to derive the value of VTO equal about to -1.5525 V:
To fill the fourth table we need the Crss capacitance graphic:
now we fill the table with pair of values to get CGD, PB and M:
