3 cards from this section. Quick, good the night before a test.
What is the main purpose of a differential amplifier?
Think about its application in reducing noise.
What is the typical base voltage used in biasing BJTs in a differential amplifier?
Relate this to the necessary V_BE drop for BJTs.
What type of signal does a differential amplifier specifically amplify?
Recall what we discussed on signal types.
True or False: The common mode gain is usually higher than the differential mode gain in differential amplifiers.
Think about the amplifier’s design purpose.
Design a differential amplifier using given parameters and calculate its operating point, small signal parameters, and output swing. Describe how each component affects the overall performance.
Utilize the operational formulas discussed throughout the session.
Given specific input signals, determine the output voltages for both differential and common modes. Graph the results and compare.
Recall the impact of differential and common mode gains on the outputs.
