The source-drain MOSFET saturation current equation is: ID=12WL μN Cox [Vgs−VT]2ID=21LW μN Cox [Vgs−VT]2 There are many similarities with the linear regime current equation; however, it's straightforward to see that we lost the dependence on the source-drain voltage, retaining ...
In the linear region (0 < –VDS < –VGS +Vth) the drain-source current is: IDS=−K((VGS−Vth)VDS−VDS2/2)(1+λ∣VDS∣) In the saturated region (0 < –VGS +Vth < –VDS) the drain-source current is: IDS=−(K/2)(VGS−Vth)2(1+λ∣VDS∣) In the preceding equatio...
