Question 1.
What does a common base amplifier do?
Show hintHide hint
Think about the configuration roles.
Question 2.
Why is capacitor C_B important?
Show hintHide hint
Remember what happens at AC ground.
3Question 3.
What is the impact of removing capacitor C_B on input resistance?
- Increases significantly
- Decreases
- Remains constant
Show hintHide hint
Think about how much voltage appears across different components.
4Question 4.

- True
- False
Show hintHide hint
Reflect on the relationship to signal application.
Question 5.
Given a common base amplifier with a collector current of 0.5 mA and an early voltage of 50V, calculate the transconductance and describe its significance.
Show hintHide hint
Use standard formulae linking collector current and transconductance.
Question 6.
Investigate how varying the input resistor affects the amplifier's overall gain without C_B. Discuss potential design considerations.
Show hintHide hint
Examine how resistances interact within the circuit.
