DC analysis of a Common Gate (CG) MOSFET Amplifier in saturation mode

This CalcTown calculator calculates the drain current and Drain to gate Voltage (V_DG) for a CG MOSFET Amplifier.

*Please enter V⁺=0 if V_DG is not required or V⁺is not given and neglect the output given for the same.

**Please enter the voltages with signs as well.
