Show hintHide hint
Think about its function as a buffer.
Question 2.
Why do we need high input impedance in amplifiers?
Show hintHide hint
Consider the effects of connecting devices together.
3Question 3.
What is the basic function of a common collector amplifier?
- To amplify voltage
- To isolate stages
- To produce high output power
Show hintHide hint
Think about its primary characteristics.
4Question 4.
True or False: The voltage gain of a common collector amplifier can be significantly greater than 1.
- True
- False
Show hintHide hint
Recall the voltage gain characteristic.
Question 5.
You have a common collector amplifier with an output resistance of 100 ohms and a load resistance of 500 ohms. Calculate the output voltage if the input voltage is 5V. Assume voltage gain approximately 1.
Show hintHide hint
Use voltage division principles.
Question 6.
If you input a high-frequency signal into a common collector amplifier where C_μ affects the gain, how would you approximate this effect on the output impedance?
Show hintHide hint
Connect behavior of capacitance at high frequencies.
