Question 1.
What is a common collector amplifier?
Show hintHide hint
Think about where the output connection is located.
Question 2.
What does high input resistance in an amplifier indicate?
Show hintHide hint
Consider the impact on signal strength.
3Question 3.
What is the primary function of a common collector amplifier?
- To amplify current
- To provide high input resistance
- Both of the above
Show hintHide hint
Consider both roles the amplifier plays.
4Question 4.
True or False: The voltage gain of a common collector amplifier is typically less than 1.
- True
- False
Show hintHide hint
Think about the behavior of the circuit with respect to voltage.
Question 5.
Design a common collector amplifier with a specified input resistance of about 10kΩ and output resistance below 100Ω. What components would you choose?
Show hintHide hint
Consider how the choice of transistors and their specifications play into these calculations.
Question 6.
A common collector amplifier shows an input capacitance of 2µF. What impact might this have on a 10kHz signal?
Show hintHide hint
Use the formula for the cutoff frequency in relation to input capacitance.
