4 cards from this section. Quick, good the night before a test.
What is the role of output resistance in an amplifier?
Consider current delivery and voltage drop.
What value does the voltage gain approach in a common collector amplifier?
Think about buffer characteristics.
What is the typical voltage gain for a common collector amplifier?
Recall the application's intent as a buffer.
True or False: The input capacitance in a common collector amplifier is generally high.
Consider its role in signal fidelity.
You have a common collector amplifier with an output resistance of 180 ohms. If it services a load resistance of 60 ohms, what form of voltage drop would you observe? Provide your calculations.
Set up the voltage divider proportionally.
If the input capacitance in a common collector amplifier is 3nF and the voltage gain is found to be 0.9, how does this influence the effective input capacitance seen by the source?
Apply Miller’s theorem appropriately.
