Question 1.
What is the role of threshold voltage in a MOSFET?
Show hintHide hint
Think about the voltage needed to start current flow.
Question 2.
What happens when V_GS is less than V_th?
Show hintHide hint
Consider what is required for a conducting path.
3Question 3.
What happens to the conductivity of the channel when V_GS is less than V_th?
- True
- False
Show hintHide hint
Refer to the definition of threshold voltage.
4Question 4.
In which region does the current flow remain nearly constant despite increases in V_DS?
- Triode Region
- Saturation Region
- Cut-off Region
Show hintHide hint
Think about how current behaves in different voltage states.
Question 5.
Design a circuit diagram for a MOSFET biased correctly to operate in the saturation region, specifying component values and conditions.
Show hintHide hint
Review the characteristics and these parameters need to function in saturation.
Question 6.
If a certain MOSFET has L = 1 µm, W = 2 µm, V_th = 0.7V, and you apply V_GS = 2V and V_DS = 3V, calculate I_DS considering saturation conditions.
Show hintHide hint
Remember the significance of W, L, and V_th while calculating I_DS.
