What is the cutoff region in a MOSFET?
Think about the gate-source voltage in relation to the threshold voltage.
Define threshold voltage (Vth).
This voltage is the turning point for current flow.
What is the primary condition for a MOSFET to be in the cutoff region?
Remember what happens below the threshold voltage.
True or False: The saturation region occurs when the drain-source voltage is very low.
Think about the behavior of current in saturation.
A n-MOSFET has a threshold voltage of 1.5V. What would happen to the current if VGS is set to 1.2V? Illustrate this behavior using an I-V curve.
Plot points on a graph to illustrate the current remaining at zero until sufficient voltage is applied.
Given an n-MOSFET with Vth=1V, calculate the drain current if VGS=3V and VDS=1V. What region of operation does this MOSFET fall into?
Review the equations for the triode operation and plug in your values.
