Challenge Problems

Push your limits with challenges.

Question 1

Design a common emitter amplifier with fixed bias and calculate the expected collector current for varying beta values. Propose a redesigned circuit for stability.

💡 Hint: Use the same supply voltage and base-emitter voltage in calculations for consistency.

Question 2

Given a specific transistor characteristic curve, analyze how varying beta affects both fixed and cell bias configurations regarding signal distortion.

💡 Hint: Refer to key performance parameters when analyzing output distortion.
