Hi. Im a first year engineering student and was having trouble on a problem. I am probably overthinking it.


Q)The n-channel MOSFET threshold voltage is +2 V. The gate voltage is +4V. The drain voltage is +5V. Is the MOSFET in the current saturation mode?




I think VGS-VT = VDS for it to be in saturation but this one is not. So is it not in saturation?

Notice that the OP gave the threshold voltage, the gate voltage, and the drain voltage. They didn't give any indication of the source voltage. Perhaps they mean the other voltages as voltages relative to the source. Perhaps the source is tied to ground. But perhaps niether of these is the case.
