Challenge Problems
Push your limits with challenges.
Question 1
Given a supply voltage of 15V, design a common base amplifier that can achieve an output swing of ±6V with an input impedance of 300Ω. Explain your calculations.
💡 Hint: Always consider the operational zones of the transistors!
Question 2
A common base amplifier yields a voltage gain of 50. If the input voltage is 0.1V, what is the output voltage? Discuss any limitations in achieving this gain.
💡 Hint: Reflect on how factors like distortion and saturation can affect real gain performance.
