Try this Formula's:

Transistor in Saturation Region:

Vds>Vgs-Vt, where Vds is the drain-source voltage, Vgs is the gate source 
voltage and Vt is the threshold voltage.

To compute the KPp and KPn, use:

Id=KPn(W/L)(Vgs-Vt)^2.

Thanks Mr Hari

But is there any formula which gives you Kn and Kp
from the technology parameters of the transistors ?
