Challenge Problems
Push your limits with challenges.
Question 1
Given a transistor with fixed parameters W = 2 mm, L = 1 mm, and a constant V_GS of 5V, calculate the expected I_DS if V_DS is increased from 2V to 10V while maintaining the other parameters the same.
💡 Hint: Refer to the current characteristics curve for the transistor type to find expected values.
Question 2
If an increase in oxide thickness (t_ox) results in halving the electron mobility, explain the effects on I_DS when V_GS and V_DS are constant.
💡 Hint: Think about the impact of mobility on the drift current in the transistor.
