Challenge Problems
Push your limits with challenges.
Question 1
A differential amplifier receives two voltages, V1 = 5V and V2 = 3V. Calculate the output for a gain of 10.
💡 Hint: Remember the formula for output voltage in terms of gain and input difference.
Question 2
Describe how a common mode rejection ratio (CMRR) can be derived from the gains of differential and common-mode signals.
💡 Hint: Think about what kind of signals the amplifier boosts versus rejects!
