Challenge Problems
Push your limits with challenges.
Question 1
Given a CE amplifier with a guaranteed beta of 200, calculate the output voltage when early voltage changes from 100V to 150V. Discuss how the feedback mechanism might alter this outcome.
💡 Hint: Refer back to the equations addressing early voltage impacts.
Question 2
Design a feedback circuit for a transistor amplifier where beta can vary between 180 and 200. Describe how the circuit can ensure output stability through feedback.
💡 Hint: Incorporate the lessons of varying beta and the necessity of feedback in your design process.
