Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A differential amplifier is designed with a differential gain of 100 and a common-mode gain of 0.2. If the CMRR is calculated, determine its value in dB.

💡 Hint: Use the CMRR formula to find the ratio.

Challenge 2 Hard

Explain why operating outside the ICMR can lead to distortion in signal output. Support your answer with examples of conditions that can cause this.

💡 Hint: Consider operational conditions in practical circuits.
