Challenge Problems

Push your limits with challenges.

Question 1

Given a CE amplifier with specific parameters, derive the small signal voltage gain when the input voltage changes with a predefined frequency.

πŸ’‘ Hint: Factor in the parameters governing gain at low vs. high frequencies.

Question 2

Analyze what happens when the operating point of the CE amplifier is shifted due to an increase in temperature and how it might affect signal distortion in practical applications.

πŸ’‘ Hint: Consider how the shift can influence both the upper and lower limits of signal amplitude.
