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?
💡 Hint: 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.
💡 Hint: Recall that CMRR indicates how much more the differential gain is than the common-mode gain.
