4 cards from this section. Quick, good the night before a test.
What is a single-ended amplifier?
Think about the reference point it uses.
Define common mode signal.
What does 'common' suggest about the signal?
What term describes the portion of the signal that is common to both inputs?
The shared signal is not the differential aspect!
True or False: A differential amplifier has one signal input.
Think about how many inputs are used!
A differential amplifier receives two voltages, V1 = 5V and V2 = 3V. Calculate the output for a gain of 10.
Remember the formula for output voltage in terms of gain and input difference.
Describe how a common mode rejection ratio (CMRR) can be derived from the gains of differential and common-mode signals.
Think about what kind of signals the amplifier boosts versus rejects!
