Challenge Problems
Push your limits with advanced challenges
Design a simple semiconductor device with specific voltage applications (V_GS and V_DS). Calculate how varying the length (L) and oxide thickness (t_ox) could impact the current flow (I_DS) with given mobility factors.
💡 Hint: Refer to relationships and formulas you have learned about current in semiconductors.
Evaluate the effect of increasing device width (W) while keeping length (L) and voltage parameters fixed on the current flow. Discuss the implications for circuit design.
💡 Hint: Think about how multiple pathways improve transportation.
