What distinguishes single-ended from differential signaling?
Think about how many wires are used in each method.
Define differential mode gain.
What part of the signal does it enhance?
Which of the following best describes differential signaling?
Consider how signals travel in pairs.
True or False: A high common mode gain in a differential amplifier is desirable.
What kind of gain do we want to minimize?
A differential amplifier has a differential gain of 50 and common mode gain of 0.2. Calculate the output voltage for an input difference of 0.5V.
Apply the formula for output voltage.
Discuss the implications of a high common mode to differential mode gain ratio in a circuit.
What issues arise from not minimizing common mode signals?
