Challenge Problems
Push your limits with advanced challenges
You have a MOSFET with W = 20 μm, L = 2 μm, V_GS = 4V, V_th = 1V, and V_DS = 3V. Calculate I_DS and detail each step.
💡 Hint: Remember the current equation. Identify how each parameter plays into the result.
Explain what changes would occur if the MOSFET's V_th increases due to fewer doping concentrations in the substrate.
💡 Hint: Think about how channel formation is impacted by doping levels.
