Given a MOSFET with parameters W=10 um, L=2 um, V_GS=5V, and V_th=1V, calculate I_DS in the triode region and explain your reasoning.
💡 Hint: What do you need to ensure to keep the MOSFET in the triode region?
A MOSFET is operated with V_GS=10V and V_th=2V while V_DS approaches and exceeds V_D(sat). Describe the behavior of I_DS in detail.
💡 Hint: Consider how saturation affects current flow in MOSFET operation.
