3 cards from this section. Quick, good the night before a test.
What is the purpose of a cascode amplifier?
Think about how it combines different amplifier stages.
Define biasing in the context of amplifiers.
Focus on how it affects performance.
What is the current gain of a common gate stage in a cascode amplifier?
Think about how current is transferred through the stages.
True or False: A cascode amplifier can increase input capacitance.
Remember the impact of voltage gain on capacitance.
Design a cascode amplifier circuit integrating both biasing sources and output impedance calculations. Explain how you would calculate the required output voltage.
Refer to gains on both stages and their biasing resistances.
Analyze the trade-offs in bandwidth extension when using cascode amplifiers compared to single-stage amplifiers, illustrating your answer with graphs.
Consider points where gain starts to drop off on the frequency response graph.
