2 cards from this section. Quick, good the night before a test.
What is the definition of trans-conductance?
Think about how amplifiers translate voltage to current.
What is feedback in amplifier circuits?
Consider how outputs can influence inputs in a loop.
What is the general effect of feedback on amplifier gain?
Remember how feedback can stabilize or modify circuit performance.
True or False: Feedback increases input resistance in electrical circuits.
Consider the benefits of higher resistance in circuit design.
Given an amplifier with a trans-conductance of 2 mS and a feedback factor β of 3, calculate the modified output voltage gain when feedback is applied.
Remember to plug in G' using the trans-conductance value and follow through the calculations.
In a circuit with an output resistance of 100kΩ and a feedback mechanism increasing it by a factor of 10, what is the new output resistance?
Look at how multiplication affects original resistance values due to feedback.
