If a MOSFET has a threshold voltage of -1.5V and V_GS = -3V, what happens if V_DS is 0V? Analyze the situation.
💡 Hint: Consider what voltage levels are needed for conduction.
Given a n-MOSFET with parameters K = 200 uA/V^2, V_th = 1V, calculate the current I_D when V_GS = 4V and V_DS = 3V, confirming which region it's in.
💡 Hint: Ensure you calculate which region the device operates based on the relationship between V_DS and the threshold.
