Challenge Problems
Push your limits with challenges.
Question 1
Calculate the emitter current I_E if the base current I_B is 50 ΞΌA and the collector current I_C is 200 ΞΌA.
π‘ Hint: Remember the relationship between base, collector, and emitter currents.
Question 2
Given the collector current is affected by the reverse bias, how would you design a circuit to optimize I_C in a high-speed application?
π‘ Hint: Think about how design changes affect charge carrier flow.
