Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a common emitter amplifier with an output swing of 5V using a V_CC of 12V. Determine resistor values needed to achieve a gain of 20 while ensuring bias point stability.

💡 Hint: Consider using the voltage divider rule and resistor configurations to stabilize the bias point.

Challenge 2 Hard

Suppose you are designing an amplifier that requires a gain factor of 50. However, doing the typical resistor configuration is providing instability. Propose an alternative layout to meet the gain requirements without losing stability.

💡 Hint: Think about how bypassing affects the gain while maintaining the necessary operating point.
