4 cards from this section. Quick, good the night before a test.
Describe what a single-ended amplifier is.
Think about how many signals it takes in.
What does a differential amplifier amplify?
Recall the significance of the two inputs.
What characterizes a single-ended amplifier?
Think about the amplifier's input configuration.
True or False: A differential amplifier complies more robustly against common-mode noise.
Recall the definition of common-mode rejection.
If you have two input voltages V1 = 12V and V2 = 8V with a differential amplifier gaining 6, what will be the output voltage? Further, if a common mode voltage of 4V is also applied, what is the effect on the output?
Focus on using the gain formula and think about what common voltage implies.
Discuss the practical implications if a differential amplifier has a very low CMRR. How would that affect its application in a noisy environment?
Think about how noise can affect communication clarity in electronic devices.
