Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a feedback oscillator circuit and explain how you would ensure it meets both the phase and gain conditions detailed in the Barkhausen Criterion.

💡 Hint: Use simulation software or calculations to model your circuit.

Challenge 2 Hard

Analyze a hypothetical circuit where the loop gain is found to be 0.8. Discuss the implications for oscillation and propose remedies to achieve the necessary condition.

💡 Hint: Think about how each component contributes to the total gain.
