Question 2.
Define voltage gain in the context of amplifiers.
Show hintHide hint
It's a measure of how much the signal is amplified.
3Question 3.
What is the primary function of a common base amplifier?
- To amplify current
- To amplify voltage
- To buffer a signal
Show hintHide hint
Consider the goals of different amplifier configurations.
4Question 4.
True or False: The input impedance of a common base amplifier is typically high.
- True
- False
Show hintHide hint
Recall the common characteristics of input impedances in amplifier circuits.
Question 5.
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.
Show hintHide hint
Reflect on how impedance and gain interact.
Question 6.
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.
Show hintHide hint
Utilize the gain formula in your calculations.
