Challenge Problems
Push your limits with challenges.
Question 1
A common base amplifier has a load capacitance of 100 pF and an output resistance of 10 kΩ. Calculate the upper cutoff frequency.
💡 Hint: Remember to convert units properly while plugging into the formula.
Question 2
If the source resistance is increased and output impedance is given as 2.83 kΩ; analyze how this would affect voltage gain in practical terms.
💡 Hint: Think of how source and load resistances interact.
