4 cards from this section. Quick, good the night before a test.
Define a current amplifier.
Think about the definition in simple terms.
What is biasing in transistor circuits?
Recall its importance in keeping devices active.
What primarily defines a current amplifier?
Focus on the type of signal it works with.
True or False: AC coupling allows DC signals to pass through an amplifier.
Think about the purpose of coupling capacitors.
Design a current amplifier circuit with an input current of 1 mA and a target output current of 20 mA. What must the current gain be?
Use the current gain formula to solve.
If a current amplifier has a current gain of 10 and experiences loading effects that reduce the output current by 1 mA, what will the effective output current be if the input current is 5 mA?
Consider both current multiplication and any reduction due to loading.
