2 cards from this section. Quick, good the night before a test.
Define output resistance in the context of amplifiers.
Think about the load and its relationship with the amplifier.
What does the term input capacitance refer to?
Consider what components might affect the input side of an amplifier.
What is the output resistance of a common collector amplifier generally considered?
Think about why output resistance is important in buffering.
True or False: A high input capacitance is preferred in voltage buffer applications.
Recall the implications of increased capacitance in circuits.
In an amplifier circuit, if the voltage gain is 0.95, find the adjusted effective capacitance contribution according to Miller's theorem, given that C_gs=10pF.
Use the formula for capacitance adjustment discussed earlier.
If you have a common collector amplifier and you want to determine its input resistance with an effective load of 50 kΩ and transconductance of 5 mS, what transform would you use?
Remember the relationship between load and how input resistance is affected by other parameters.
