Challenge Problems
Push your limits with advanced challenges
Design a common emitter amplifier circuit ensuring the DC operating point remains stable despite variations in beta. What compensating methods might you employ?
💡 Hint: Consider how feedback can help maintain consistent performance.
Given a transistor with a beta of 100, calculate the new operating point if the beta increases to 200, assuming all other conditions remain the same. Discuss the implications of this change.
💡 Hint: Remember the influence of beta on collector current and thus on voltage calculations.
