4 cards from this section. Quick, good the night before a test.
What happens in the cutoff region of a MOSFET?
Think about whether the device is conducting or not.
Define threshold voltage.
Consider the gate-source relationship.
What is the cutoff region in a MOSFET?
Remember the definition of cutoff.
In which region of operation does current stabilize?
Think about when the current doesn't change with voltage.
Determine the operating region and calculate the current for an n-MOSFET given V_GS = 4V, V_DS = 3V, and V_th= 1.5V, where K = 0.5 mA/V².
Identify the operating region first by calculating V_GS - V_th.
Create a scenario where a p-MOSFET might not turn on despite a positive gate-source voltage: explain.
Think about the charge carrier flow and how biased voltage affects it.
