Question 1.
What happens to the base width when the collector-base voltage increases?
Show hintHide hint
Think about the depletion region's effect.
Question 2.
What does the parameter β represent in a transistor?
Show hintHide hint
Recall its definition.
3Question 3.
What happens to the base width when V_CB is increased?
- It increases
- It decreases
- It stays the same
Show hintHide hint
Think about the physical changes in the junction.
4Question 4.
The relationship between α and β is integral for understanding BJT current gain. True or False?
- True
- False
Show hintHide hint
Reflect on how these parameters function together in amplifying current.
Question 5.
Design a circuit that utilizes BJTs to achieve a specific amplification gain. Explain how you would determine the necessary biasing conditions and the impact of base width reduction at higher voltages.
Show hintHide hint
Use the α and β relationships to guide your biasing decisions.
Question 6.
If the collector current in a BJT is given as 10 mA with β = 100, calculate the base current and determine how changes in V_CB could affect this set-up.
Show hintHide hint
Think about how I_B and I_C relate and how voltage influences this relationship.
