Challenge Problems
Push your limits with challenges.
Question 1
Design a Class A amplifier with a supply voltage of 15V. If you choose a quiescent current of 15mA, calculate the efficiency when the maximum undistorted AC output is 3V.
💡 Hint: Consider boundaries of output power vs. input power.
Question 2
Discuss the trade-off scenarios between efficiency and fidelity in Class A amplifiers while offering a design suggestion to minimize distortion.
💡 Hint: Evaluate the balance between how much power a Class A amplifier can realistically use versus delivering a clean signal.
