2 cards from this section. Quick, good the night before a test.
What is the primary purpose of cascading amplifiers?
Think about why we connect multiple amplifiers in a sequence.
What effect do buffers have in amplifier circuits?
Consider the basic function of buffers in electronic circuits.
What happens to the gain when cascading amplifiers?
Recall the interaction between stages.
Using a buffer between cascaded amplifiers improves:
Think about the function of buffers in amplifiers.
Design a circuit with two cascaded CE amplifiers and a buffer. Present the schematic and explain the considerations in your design.
Think about how the impedance will affect the signal.
Analyze the effects of not using buffers in a cascaded amplifier setup that has a significant gain drop. What design flaws might cause this?
Reflect on the role of input and output resistance.
