2 cards from this section. Quick, good the night before a test.
Define a current amplifier.
Think about what the input and output signals are.
What is the purpose of DC biasing in amplifiers?
Consider where we want the transistor to operate.
What is the function of DC biasing in a current amplifier?
Consider the operational state of the transistor.
True or False: The loading effect increases the output current of the amplifier.
Reflect on how added load affects current flow.
Design a current amplifier with a specified gain of 10. Explain how you would set up the DC bias and loading resistances.
Use the gain formula and basic principles of circuit design.
A current amplifier feeding into a load resistance of 1k ohm shows a 20% drop in output current. Calculate the unloaded current gain given the input current.
Use the relationship equations discussed in the section.
