What is the primary function of a Difference Amplifier?
Think about what the name suggests.
Define Common-Mode Rejection Ratio (CMRR).
What does CMRR specifically measure?
What does a Difference Amplifier primarily output?
Consider what 'difference' means.
True or False: A Difference Amplifier has no effect on common-mode signals.
Think about its function.
Design and calculate the output of a Difference Amplifier circuit if V1 = 3V, V2 = 1V, R1 = R2 = 10kΩ, and R3 = R4 = 20kΩ. What would be the output voltage?
Use the formula for the output of a Difference Amplifier.
Given a Difference Amplifier with a CMRR of 80 dB and a common-mode gain of 0.01, calculate the differential voltage gain.
Recall that CMRR indicates how much more the differential gain is than the common-mode gain.
