Question 1.
What is the role of the coupling capacitor (C_B) in an amplifier circuit?
Show hintHide hint
Think about how AC signals interact with DC.
Question 2.
What happens to the voltage gain when C_B is removed?
Show hintHide hint
Consider the involvement of voltage at the input and output.
3Question 3.
What is one major effect of removing C_B in an amplifier?
- A) Increases gain
- B) Decreases gain
- C) No effect on gain
Show hintHide hint
Think about the function of C_B in facilitating voltage.
4Question 4.
True or False: Removing C_B will increase the input resistance of the amplifier.
- True
- False
Show hintHide hint
Reflect on how input resistance functions in the circuit.
Question 5.
You have a common base amplifier with a known input voltage of 5V. If the gain with C_B connected is 108, what is the expected output voltage if C_B is disconnected?
Show hintHide hint
Consider the effect of voltage gain when changing configuration.
Question 6.
Design an equivalent circuit of a common base amplifier that minimizes loss without using C_B, describing your rationale.
Show hintHide hint
Think about alternative methods of directing and managing signal flow.
