Challenge Problems
Push your limits with advanced challenges
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.
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.
