Question 1.
What is the role of feedback in amplifier circuits?
Show hintHide hint
Think about how feedback influences circuit amplification.
Question 2.
Define trans-impedance.
Show hintHide hint
What is being converted within the amplifier?
3Question 3.
What is the effect of feedback on trans-conductance?
- Increases it
- Decreases it
- No effect
Show hintHide hint
Consider the purpose of feedback in stabilizing the amplifier.
4Question 4.
True or False: Feedback can increase both input and output resistance.
- True
- False
Show hintHide hint
Remember the PIER concept.
Question 5.
Given a feedback circuit with R = 1kΩ, calculate the new input resistance after implementing feedback that increases it by 50%.
Show hintHide hint
Apply the percentage increase to the original resistance.
Question 6.
Design a feedback circuit with target trans-impedance of 10kΩ and adjust R values to ensure G remains effective.
Show hintHide hint
Remember how Z relates to G and R.
