4 cards from this section. Quick, good the night before a test.
What is the primary function of a single-ended amplifier?
Think about where the signal is amplified regarding ground.
Define differential gain.
Consider how two signals are used together.
What does a differential amplifier do?
Think about how this amplifier is designed.
True or False: High common mode gain is desirable in a differential amplifier.
Reflect on why we want to reduce common mode effects.
You have two periodic signals, v_in1 = 3sin(ωt) and v_in2 = 1sin(ωt); calculate the differential output with A_d = 15 and A_c = 3.
Don't forget to use both the gains properly in the equations.
Discuss the implications of having a non-zero A_c_d on the design criteria of a differential amplifier.
Consider how this may influence circuit functionality.
