Question 1.
What is a common base amplifier intended for?
Show hintHide hint
Think about the amplifier's primary function.
Question 2.
How does source resistance affect voltage gain?
Show hintHide hint
Consider the division of voltage between source resistance and input impedance.
3Question 3.
What is the primary use of a common base amplifier?
- Voltage amplification
- Current amplification
- Power amplification
Show hintHide hint
Think about the main goal of an amplifier.
4Question 4.
If source resistance increases, what happens to the voltage gain?
- True
- False
Show hintHide hint
Reflect on voltage division effects.
Question 5.
A common base amplifier has a collector resistance of 3 kΩ and source resistance of 1 kΩ. If the voltage input is 1V, compute the output voltage and check if it satisfies the condition for a good amplifier.
Show hintHide hint
Use the voltage divider rule.
Question 6.
Design a common base amplifier circuit considering a source resistance of 50 kΩ and find the parameters that will optimize performance.
Show hintHide hint
Remember the relationships between source resistance, gain, and bandwidth.
