2 cards from this section. Quick, good the night before a test.
What is β in a transistor?
You can find this in the glossary or check the definitions discussed.
What happens to the operating point if Early voltage increases?
Think about how voltage influences the transistor's operation!
What does an increase in Early voltage typically do to the stability of a CE amplifier?
Think about how Early voltage relates to the performance across varying conditions.
True or False: Feedback in an amplifier circuit will always increase gain.
Remind yourself of the role feedback plays in circuits.
You are asked to design a CE amplifier with expected β of 150. If β unexpectedly decreases to 130, discuss how you will redesign the circuit to maintain stability.
Recall the feedback principles discussed.
Given a CE amplifier configuration, calculate the new operating point if Early voltage decreases drastically after changes. What calculations must be re-evaluated?
Understand how Early voltage affects the voltage across the transistor.
