Question 1

What is the key difference between differential mode and common mode?

  • Differential mode amplifies both inputs equally.
  • Common mode amplifies the difference between inputs.
  • Differential mode amplifies the difference between inputs.

πŸ’‘ Hint: Focus on their definitions.

Question 2

True or False: Common mode gain is always zero.

  • True
  • False

πŸ’‘ Hint: Think about the conditions under which outputs can be equal.

Challenge Problems

Push your limits with challenges.

Question 1

Design a differential amplifier that can handle input signals of amplitudes up to 10V with a gain of 20. Calculate the necessary component values.

πŸ’‘ Hint: Use the relationship A = R_f/R_i for feedback and input resistors.

Question 2

Given a common mode voltage of 2V and a differential gain of 15dB, what will be the output voltage if both inputs experience the same signal?

πŸ’‘ Hint: Use logarithmic conversions for dB if necessary.
