Question 1

What is the primary role of the base-emitter junction in a BJT?

  • To block current
  • To allow current flow
  • To limit voltage

💡 Hint: Think about the current flow direction in a forward-bias state.

Question 2

The collector current (I_C) is dependent on which voltage in the BJT operation?

  • V_CB
  • V_BE
  • Both V_CB and V_BE

💡 Hint: Focus on the primary voltage influencing collector behavior.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the emitter current I_E if the base current I_B is 50 μA and the collector current I_C is 200 μA.

💡 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?

💡 Hint: Think about how design changes affect charge carrier flow.
