Challenge Problems
Push your limits with challenges.
Question 1
How would you calculate the β if the collector current in a BJT is 30 mA and the base current is 0.2 mA?
💡 Hint: Use the formula β = I_C/I_B.
Question 2
A BJT with a base width of 0.1μm has a diffusion constant for electrons of 25 cm²/s. If the emitter doping is high, what factors should you consider to maximize β?
💡 Hint: Consider the role of charge dynamics in a BJT.
