Question 1.
What is the typical voltage gain of a common base amplifier?
Show hintHide hint
Think about how voltage gain is expressed as an output over input ratio.
Question 2.
What is the input impedance for the common base amplifier?
Show hintHide hint
Remember, low impedance means the amplifier draws more current.
3Question 3.
What is the primary advantage of a common base amplifier?
- Higher input impedance
- Lower noise
- Higher voltage gain
- Better high-frequency performance
Show hintHide hint
Consider the effects of capacitance on frequency response.
4Question 4.
True or False: A common base amplifier typically has a high input impedance.
- True
- False
Show hintHide hint
Recall the typical values for input impedance in different configurations.
Question 5.
Design a common base amplifier circuit with specific values for DC biasing and analyze its performance considering a source resistance of 5 kΩ.
Show hintHide hint
Make sure to assess how each component value affects the overall gain.
Question 6.
Consider a scenario where the common base amplifier is improperly biased. Calculate and interpret how the operating point affects the overall gain.
Show hintHide hint
Think about how changing bias points impacts current flow and thereby gain.
