Challenge Problems
Push your limits with challenges.
Question 1
Design a cascading amplifier system with two stages: the first has a gain of 150 and the second, 200. However, the input impedance of the second stage is only 50% effective due to its loading effect. Calculate the overall gain.
💡 Hint: Don't forget to include the attenuation factor due to loading.
Question 2
Explain how a change in temperature could affect the bias point stability of a cascaded amplifier. Provide a real-world example.
💡 Hint: Consider how components in circuits respond to temperature changes.
