Challenge Problems
Push your limits with challenges.
Question 1
Design a MOSFET circuit where you require a specific I_DS of 20 mA. Given V_GS, V_th, and a fixed L value, determine W required.
💡 Hint: Remember that K is a device constant reflecting on internal parameters.
Question 2
Evaluate how the MOSFET's characteristics switch from triode to saturation region with varying V_DS while keeping V_GS constant.
💡 Hint: Identify the threshold value where the dependency shifts dramatically.
