Challenge Problems
Push your limits with challenges.
Question 1
Given a BJT with a forward voltage of 0.7V and a reverse saturation current of 1μA, calculate the current flowing through the base-emitter junction.
💡 Hint: Use the exponential relation to calculate.
Question 2
If the doping concentrations of the emitter, base, and collector are 10^20 cm^-3, 10^15 cm^-3, and 10^18 cm^-3 respectively, analyze how these concentrations will affect current flow in different bias conditions.
💡 Hint: Think critically about how carrier concentration affects mobility.
