Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier with a specified gain of -20. If Rio = 10 kΩ, calculate the values for Re needed to maintain stability with varying β.
💡 Hint: Consider using ideal values for Rc initially, then assess Re.
Question 2
You need to analyze how varying Rc impacts overall gain while having Re fixed at 470 Ω. Discuss your findings.
💡 Hint: Employ the gain equation and examine how alterations affect the R factors.
