Challenge Problems

Push your limits with challenges.

Question 1

Using a cascode amplifier design with a given transistor configuration, calculate the expected gain and input capacitance when switching the load resistance from 5 kΩ to 50 kΩ.

💡 Hint: Use the relationship that gain = voltage output per voltage input.

Question 2

Design a scenario where the cascode amplifier's performance is critically beneficial over a regular CE amplifier in a high-frequency RF application.

💡 Hint: Consider factors like output resistance, frequency response, and bandwidth.
