3 cards from this section. Quick, good the night before a test.
Define voltage gain in the context of an amplifier.
Think about the relationship between input and output in amplifiers.
What does the emitter resistance (R_E) do in a circuit?
Consider its impact on circuit performance.
What is the voltage gain of a common emitter amplifier defined as?
Think about how an amplifier enhances signals.
True or False: An increase in emitter resistance generally increases the overall gain of an amplifier.
Consider the trade-offs of resistance in amplifiers.
Given a circuit with a transconductance of 25 mS and collector resistance of 5 kΩ, determine the voltage gain if the emitter resistance is 1 kΩ.
Plug in the values carefully into the formula.
Analyze the effect of increasing emitter resistance on the voltage gain. What phenomenon occurs and why should designers be cautious?
Consider the role of resistance in amplification.
