Question 1.
What does voltage swing refer to in an amplifier?
Show hintHide hint
Think about how much the output can fluctuate.
Question 2.
Define input impedance in your own words.
Show hintHide hint
Consider what an impedance represents.
3Question 3.
What is the maximum output voltage swing an amplifier with a 12V supply can realistically achieve?
- ±6V
- ±4V
- ±12V
Show hintHide hint
Remember how the power supply limits influence output.
4Question 4.
True or False: The input impedance is irrelevant in common base amplifier design.
- True
- False
Show hintHide hint
Think about how signal integrity relies on impedance matching.
Question 5.
Given a supply voltage of 15V, design a common base amplifier that can achieve an output swing of ±6V with an input impedance of 300Ω. Explain your calculations.
Show hintHide hint
Always consider the operational zones of the transistors!
Question 6.
A common base amplifier yields a voltage gain of 50. If the input voltage is 0.1V, what is the output voltage? Discuss any limitations in achieving this gain.
Show hintHide hint
Reflect on how factors like distortion and saturation can affect real gain performance.
