DC Analysis of a Self-Biased CS MOSFET Circuit in saturation mode

This CalcTown calculator calculates the DC parameters like the I_DQ and V_DS values of a Common Source (CS) self-biased MOSFET circuits, with the MOSFET working in the saturation mode.

*Please note that the body effect has been neglected.
