Question 2.
What does feedback do in amplifiers?
Show hintHide hint
Recall the two types of feedback discussed.
3Question 3.
What is the primary function of a trans-conductance amplifier?
- Convert voltage to current

4Question 4.
True or False: Negative feedback always increases circuit gain.
- True
- False
Show hintHide hint
Consider the role of stability in feedback networks.
Question 5.
Design a trans-conductance amplifier with specified parameters including a gain factor of 50 and analyze the output resistance with feedback. Explain the adjustments needed for non-ideal conditions.
Show hintHide hint
Consider the relationships among voltage, current, and feedback in your design.
Question 6.
If a trans-conductance amplifier operates with a finite input resistance of 10kΩ and an output resistance of 4kΩ, calculate the expected output resistance under negative feedback with a β of 0.1.
