2 cards from this section. Quick, good the night before a test.
Define feedback in the context of amplifier circuits.
Consider the role of output in adjusting input.
List the main configurations of feedback used in amplifiers.
Think about how input and output signals are connected.
What is the primary purpose of feedback in amplifier circuits?
Think of why we would want to return output to input.
True or False: Voltage feedback always increases the gain of an amplifier.
Recall how feedback works to stabilize rather than enhance gain.
Design a feedback circuit using current-shunt configuration to stabilize transconductance. Explain your choice.
Refer back to the impacts of various configurations.
Evaluate the effects of feedback on a BJT amplifier's stability when using different configurations. Provide a comparative analysis.
Think about what each feedback does to the gain.
