Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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

💡 Hint: Factor in the parameters governing gain at low vs. high frequencies.

Challenge 2 Hard

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.

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