Challenge Problems

Push your limits with challenges.

Question 1

You design a differential amplifier with R_C values of 4.7 kΩ and a total DC supply of 30V. If the measured output at max input swing is observed to be 18V, calculate the theoretical differential gain.

💡 Hint: Remember to consider the measured values carefully.

Question 2

Consider an Op-Amp circuit designed with R_in = 1 kΩ and R_f = 10 kΩ. Calculate the gain and determine the significance of the phase difference observed.

💡 Hint: Reflect on phase as a key aspect of how outputs behave relative to inputs!
