Challenge Problems
Push your limits with advanced challenges
You are tasked with designing a common-base amplifier to amplify a weak audio signal with a specific source impedance of 1 kΩ. Discuss the implications and adjustments that must be made for optimum performance.
💡 Hint: Reflect on how impedance and gain interact.
If a common base amplifier has a specified gain of 50 and an input resistance of 20Ω, calculate how much voltage appears across the output if the input signal is 0.1V.
💡 Hint: Utilize the gain formula in your calculations.
