I-V relation and transconductance for saturation mode NMOS

This CalcTown calculator calculates the output current and transconductance in a NMOS in saturation mode.

Hence, the conditions 1. V_GS>V_TN and 2. V_DS>V_GS-V_TN are satisfied.

*Please enter 0 in the lambda and V_DS field if the body effect is to be neglected.

** For potential divider bias circuits, gate-to-source voltage (V_GS)=R_G2VDD/(R_G1+R_G2)
