Question 2.
Define β in the context of BJTs.
Show hintHide hint
Think about how the collector current relates to the base current.
3Question 3.
What are the two types of BJTs?
- n-p-n and p-n-p
- n-n-p and p-p-n
- p-n and n-p
Show hintHide hint
Think about the layout of the semiconductor materials.
4Question 4.
True or False: The collector current is always larger than the base current in a properly functioning BJT.
- True
- False
Show hintHide hint
Consider the definition of the gain parameter β.
Question 5.
If a BJT has a β of 200 and the collector current is 20mA, calculate the base current. What happens to the collector current if the base current is increased to 0.1mA?
Show hintHide hint
Understanding the relationship is crucial.
Question 6.
Design a simple circuit using a BJT that amplifies an input signal and describe the biasing method used.
Show hintHide hint
Focus on ensuring the BJT remains in the active region.
