Challenge Problems
Push your limits with challenges.
Question 1
Derive the effect of channel length modulation on the overall current in a MOSFET.
💡 Hint: Analyze the relationship between V_DS and channel length as it changes.
Question 2
Given a MOSFET with specific values for W, L, V_GS, and V_th, calculate I_DS under both triode and saturation conditions.
💡 Hint: Ensure to identify when the MOSFET switches from triode to saturation.
