Challenge Problems
Push your limits with challenges.
Question 1
Design a feedback circuit where the output resistance must not exceed 100 Ω. Given R = 5 kΩ and β = 200, how will you adjust values to meet this criterion?
💡 Hint: What factors in the feedback mechanism can help control resistance?
Question 2
In a common emitter amplifier circuit with a given feedback network, Z' is measured at 300 kΩ. If the input resistance is 10 kΩ, how might this affect the design?
💡 Hint: Consider how Z' influences total circuit performance.
