An NMOS transistor is operating in the saturation region and is having a W/L ratio equal to 20. If the value of the threshold voltage is 0.5 V and the parameter kn' is equal to 90 mA/V2 then find out the value of the drain current. Assume that the value of the gate to source voltage VGS is 2.55 V.
If the gate-source PN junction is forward- biased with a small voltage, the JFET channel will "open" a little more to allow greater currents through. However, the PN junction of a JFET is not built to handle any substantial current itself, and thus it is not recommended to forward-bias the junction under any circumstances. yes No both
