2 cards from this section. Quick, good the night before a test.
What are the four basic feedback configurations?
Think of how voltage and current are used in feedback.
What is a desensitization factor?
It relates to the impact of feedback on gain.
What is the effect of voltage-shunt feedback on input resistance?
Think about how feedback modifications work.
True or False: The current-series configuration typically decreases input resistance.
Consider the definition of 'series' in the context.
Given a BJT amplifier operating with a voltage-shunt feedback, calculate its expected input and output resistance knowing the base resistance is 1kΩ.
Start by applying the relationship described earlier regarding the relationships of resistance in feedback.
Design a circuit using op-amp feedback for current stabilization and analyze the expected outcomes.
Use circuit simulation tools to visualize the gains and output effects.
