Question 1.
What is the typical maximum gain of a single CE amplifier stage?
Show hintHide hint
Recall the maximum voltage gain mentioned earlier.
Question 2.
What does output swing refer to?
Show hintHide hint
Consider what happens when the output signal exceeds the power supply limits.
3Question 3.
What is the approximate maximum gain of a single stage CE amplifier?
- 150
- 200
- 230
Show hintHide hint
Think back to the lecture on single-stage limitations.
4Question 4.
Cascading amplifiers can lead to decreased overall gain due to:
- Loading effects
- Increased power dissipation
- Reduced input resistance
Show hintHide hint
Consider how resistance affects signal transfer.
Question 5.
You are tasked with designing a two-stage CE amplifier using fixed bias configuration. The first stage has a voltage gain of 120, and the second stage needs to achieve 200. Calculate the required input and output resistances to maintain gain without distortion.
Show hintHide hint
Use gain formulas and consider implications of resistance values.
Question 6.
Create a scenario where excessive feedback resistor values create instability in a CE amplifier. Describe how you would adjust these to get back to optimal gain.
Show hintHide hint
Reflect on how feedback impacts overall performance metrics.
