Challenge Problems
Push your limits with challenges.
Question 1
Design a differential amplifier circuit that outputs a signal of 5V given two input signals of 3V and 1V, if the gain A_d is to be maintained at 2. Describe the steps involved.
💡 Hint: Think about how the relationship between inputs defines the output under given amplification.
Question 2
Explain what happens to the output of differential amplifiers if both input signals experience the same interference from noise. How can this scenario be mitigated?
💡 Hint: Explore the concepts of noise reduction in amplifiers and how differential circuits aid performance.
