Challenge Problems
Push your limits with challenges.
Question 1
Explain the impact of increasing input capacitance on the bandwidth of a cascode amplifier in comparison to a common-emitter amplifier. What precautions would you take to maximize performance?
💡 Hint: Think about the inverse relationship between capacitance and bandwidth.
Question 2
For a cascode amplifier where the total input capacitance is 20 pF, and output resistance is 50 kΩ, calculate the cutoff frequency. How can you ensure this frequency meets system requirements?
💡 Hint: Use the formula for frequency cutoff based on RC time constant.
