2 cards from this section. Quick, good the night before a test.
What is the definition of trans-impedance?
Think about the amplifier's gain.
Explain the function of negative feedback.
Consider how feedback can improve stability.
What does feedback do in amplifier circuits?
Remember the primary purpose of feedback.
True or False: Feedback increases input resistance.
Think about its impact on signal reception.
Design a feedback circuit where the output resistance must not exceed 100 Ω. Given R = 5 kΩ and β = 200, how will you adjust values to meet this criterion?
What factors in the feedback mechanism can help control resistance?
In a common emitter amplifier circuit with a given feedback network, Z' is measured at 300 kΩ. If the input resistance is 10 kΩ, how might this affect the design?
Consider how Z' influences total circuit performance.
