Push your limits with advanced challenges
Develop a design for a transistor amplifier using Fixed Bias. Describe the steps and calculations to ensure you reach a desired Q-point of 3mA. Discuss potential stability issues.
💡 Hint: Use the transistor equations for current relationships.
For a Voltage Divider Bias circuit, given VCC=15V, design a circuit with a target IC of 5mA. Provide complete calculations for R1, R2, and RE, ensuring to explain how stability will be achieved.
💡 Hint: Remember to check that the current through R2 is much larger than IB.
