Question 1
What defines the saturation region in a MOSFET?
- I_DS is constant
- Voltage across is high
- V_GS < V_th
💡 Hint: Think about the behavior of current in relation to V_DS.
Question 2
True or False: Increasing V_DS always increases I_DS.
- True
- False
💡 Hint: Consider the effects of saturation on current flow.

Challenge Problems
Push your limits with challenges.
Question 1
Given a MOSFET with W = 2um, L = 1um, V_th = 1V, V_GS = 5V, and V_DS = 2V, calculate I_DS assuming K=1mA/V^2. If L is reduced by 10%, how does I_DS change?
💡 Hint: Calculate both before and after the change using the I_DS expression.
Question 2
Analyze how increasing V_GS affects the transition point from triode to saturation for a given MOSFET with fixed V_DS.
💡 Hint: Relate your findings to the expressions you've learned for I_DS.
