Question 1.
What does I_DS represent in a PMOS transistor?
Show hintHide hint
Think about what current flows in a transistor.
Question 2.
Define V_th.
Show hintHide hint
What voltage allows the PMOS to turn on?
3Question 3.
What is the primary factor determining I_DS in a PMOS transistor?
- Length of the channel
- Width of the channel
- Both length and width
Show hintHide hint
Think about how you can change resistance.
4Question 4.
In which region does a PMOS transistor primarily remain in constant current mode?
- True
- False
Show hintHide hint
Does the current change much when voltage increases in saturation?
Question 5.
Describe how the pinch-off condition affects the PMOS transistor and calculate the impact on I_DS if V_DS = V_GS - V_th.
Show hintHide hint
Visualize it as the current ceasing to increase beyond a certain V_DS.
Question 6.
Given a PMOS with W = 20µm, L = 2µm, V_GS = 5V, V_th = 2V, and V_DS = 4V, find I_DS assuming K = 50μA/V^2.
