2 cards from this section. Quick, good the night before a test.
Define trans-impedance in amplifiers.
Think about how voltage relates to current in the context of an amplifier.
What is the role of negative feedback?
Consider how it affects the gain.
What is the primary purpose of using negative feedback in amplifiers?
Remember the core function of feedback.
True or False: Shunt feedback increases both input and output resistance.
Think about how feedback configurations affect resistance.
Design a feedback circuit with β = 50 and R = 10 kΩ. Discuss the expected input and output resistances based on design choices.
Calculate using provided formulas and consider feedback impacts.
Analyze the stability implications of a feedback circuit with increased β. What performance trade-offs should be anticipated?
Think about how stability impacts amplifier applications.
