4 cards from this section. Quick, good the night before a test.
Define voltage gain in the context of amplifiers.
Think about how signals are increased in strength.
What does input resistance affect in an amplifier?
Consider how the input stage receives the signal.
What is the voltage gain of an amplifier with an output of 10V and input of 2V?
Use the gain formula!
True or False: Output swing is the range of output that causes distortion.
Recall the correct definition.
An amplifier has a voltage gain of 150 and needs to drive a load of 500Ω. If the input signal is 1V, determine the output voltage, assuming ideal conditions.
Think about how the amplifier drives the required load.
Discuss the drawbacks of high power dissipation in an amplifier circuit and how it can affect the amplifier's performance.
Consider thermal limits for reliability.
