Question 1
Design a differential amplifier with a target CMRR of 60 dB using specific values for \(A_{dm}\) and \(A_{cm}\). What are the implications of selecting these values?
💡 Hint: Consider how selecting larger gains affects real-world implementation.
Question 2
Given a differential amplifier with \(A_{dm} = 200\) and \(A_{cm} = 2\), is the performance satisfactory in environments with heavy noise? Justify your answer using CMRR.
💡 Hint: Evaluate if the CMRR is sufficiently high for practical applications.
