Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier circuit with given specifications targeting a specific lower cutoff frequency. Discuss how you would select component values and justify your decisions regarding R_E and C values.
💡 Hint: Use the formula for cutoff frequency to link R and C.
Question 2
You have an amplifier circuit where increasing R_E from 1kΩ to 10kΩ dramatically reduced gain. Provide a mathematical analysis of this scenario, including the implications of stability and what design considerations you recommend.
💡 Hint: Reflect on how changes in R_E affect the gain as described in class.
