Question 1.
What happens at VGS = 0 in an n-channel enhancement-mode MOSFET?
Show hintHide hint
Think about the initial state of the device.
Question 2.
Describe what occurs when VGS exceeds Vth.
Show hintHide hint
Focus on the relationship between voltage and current flow.
3Question 3.
At what condition does an n-channel enhancement-mode MOSFET begin conducting current?
- When VGS = 0
- When VGS > Vth
- When VDS > Vth
Show hintHide hint
Remember the threshold voltage's role.
4Question 4.
True or False: An n-channel enhancement-mode MOSFET has a conductive channel at zero gate-source voltage.
- True
- False
Show hintHide hint
Recall the definition of enhancement-mode.
Question 5.
An n-channel enhancement-mode MOSFET has a threshold voltage of 3V and a gain factor k of 0.5 mA/V^2. Calculate the drain current (ID) when VGS is 5V in the saturation region.
Show hintHide hint
Focus on plugging in the values correctly into the formula.
Question 6.
If VGS is increased gradually past the threshold voltage, how would you expect the ID to behave in the different operating regions?
Show hintHide hint
Think about the relationship between VGS and the conductive channel's behavior.
