Challenge Problems
Push your limits with advanced challenges
Design a differential amplifier that can handle input signals of amplitudes up to 10V with a gain of 20. Calculate the necessary component values.
💡 Hint: Use the relationship A = R_f/R_i for feedback and input resistors.
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?
💡 Hint: Use logarithmic conversions for dB if necessary.
