Question 1.
What is the purpose of an active load in an amplifier?
Show hintHide hint
Think about how it impacts performance.
Question 2.
Define negative feedback in your own words.
Show hintHide hint
Consider feedback's effect on the input.
3Question 3.
What is the main benefit of using an active load in amplifiers?
- Improves noise level
- Enhances voltage gain
- Increases dissipation
Show hintHide hint
Think about performance improvement.
4Question 4.
True or False: Without a bypass capacitor, the operating point is always optimal.
- True
- False
Show hintHide hint
Review feedback effects.
Question 5.
Design an amplifier circuit using active load principles and calculate the expected gain and output resistance without and with a bypass capacitor. Highlight the differences.
Show hintHide hint
Consider resistive paths and transistor parameters.
Question 6.
If an amplifier without feedback achieves a gain of 40 and one with negative feedback is expected to drop to 20, discuss the potential role of an active load in recovering some of that lost gain.
