Challenge Problems
Push your limits with advanced challenges
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.
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.
