Challenge Problems
Push your limits with challenges.
Question 1
Design a cascode amplifier with a given input resistance of 5 kΩ and an output load resistance of 10 MΩ. Calculate the expected gain and bandwidth and discuss the influence of the Miller effect.
💡 Hint: Consider all forms of resistance and how they impact your design choices.
Question 2
Evaluate the performance degradation in bandwidth if the output resistance rises unnaturally high due to component selection in a cascode amplifier. Propose solutions to manage bandwidth.
💡 Hint: Think about alternatives to manage high resistance efficiently.
