Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a set of measured gains: A_d = 75 and A_cm = 0.25, calculate CMRR in dB.

💡 Hint: Start by calculating the CMRR first before converting to decibels.

Challenge 2 Hard

Why does a higher value of resistance at the emitter improve the differential amplifier's performance?

💡 Hint: Consider how the specifications of components affect overall circuit performance.
