Challenge Problems
Push your limits with challenges.
Question 1
A common base amplifier must maintain a voltage gain of 150 with source resistance of 5kΩ. If the desired load resistance is 1kΩ, calculate the required transconductance.
💡 Hint: Adjusting R_C will be key to achieving the desired outcome.
Question 2
How will increasing source resistance impact the upper cutoff frequency in a common base amplifier setup? Demonstrate with calculations.
💡 Hint: Track how different resistances affect your frequency response.
