Question 1
What is the role of V_{th} in the triode equation?
- It sets the gate voltage
- It determines if the MOSFET is turned on
- It regulates the current flow
π‘ Hint: Think about what happens when the gate voltage is lower than V_{th}.
Question 2
True or False: The larger the value of W/L, the less current a MOSFET can carry.
- True
- False
π‘ Hint: Consider how the physical structure affects performance.

Question 1
A MOSFET with W/L = 15, ΞΌ_n = 700 cmΒ²/VΒ·s, and C_{ox} = 1.5 fF/ΞΌmΒ² needs to be evaluated at V_{GS} = 5V, V_{th} = 1V, V_{DS} = 0.2V. Calculate I_D and discuss how changes in W/L affect I_D.
π‘ Hint: Use the triode equation step by step and consider varying W/L at the end.
Question 2
If a circuit requires a specific current flowing through a MOSFET, how would you manipulate the parameters like V_{GS}, V_{th}, and W/L to achieve this? Provide a concrete example.
π‘ Hint: Think about the effects of each parameter on current flow.
