Challenge Problems
Push your limits with challenges.
Question 1
A cascode amplifier shows a gain of 50, but the input capacitance is causing concern. If the output stage resistance is increased, predict the impact on bandwidth and justify.
💡 Hint: Use the relationship between capacitance and frequency response.
Question 2
Design a cascode amplifier with a target gain of 200 and analyze how varying the input resistance affects overall performance.
💡 Hint: Exploit the gain relationship while keeping resistance in mind for your calculations.
