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