Challenge Problems
Push your limits with challenges.
Question 1
Develop a common emitter amplifier circuit with given parameters (Vcc=15V, R1=2kΩ, transistor β=150) and evaluate its performance under random variations in β and Early voltage. Provide design justification.
💡 Hint: Analyze how the resistance values are tailored to ensure consistent performance.
Question 2
Given a situation where the Early voltage varies unexpectedly, describe how you would adjust the design of a CE amplifier to counteract such variations.
💡 Hint: Think about circuit diagrams illustrating these concepts.
