Question 1.
What are the main regions of an n-p-n BJT?
Show hintHide hint
Think of the transistor's structure.
Question 2.
What does applying forward bias do to a junction?
Show hintHide hint
Consider what happens to current flow.
3Question 3.
What is the role of the base-emitter junction in a BJT?
- It allows current to flow
- It blocks current completely
- It regulates temperature
Show hintHide hint
Remember what forward bias means.
4Question 4.
The current gain ratio of a BJT is denoted by which Greek letter?
- α
- β
- γ
Show hintHide hint
Think of how current is amplified.
Question 5.
Given a BJT with a β value of 100, calculate the collector current if the base current is 0.1 mA.
Show hintHide hint
Apply the beta relationship to find the collector current.
Question 6.
If the base width of a BJT is reduced from 0.1 µm to 0.05 µm, discuss the impact on the β value and give possible reasons for this effect.
Show hintHide hint
Think about how the electrons traverse the base region.
