4 cards from this section. Quick, good the night before a test.
What is the primary function of a current amplifier?
Think about the name of the amplifier.
What does DC bias do in a BJT?
Consider what is needed to keep it functioning.
What is the main function of a current amplifier?
Think about what 'current amplifier' implies.
True or False: In a current amplifier, the load affects the output current measured.
Reflect on our discussions about loading effects.
If you connect a load resistance of 50Ω to a current amplifier with an unloaded current gain of 10, calculate the approximate output current if the input current is 2mA.
Consider how current divides between loads.
Design a simple current amplifier circuit using a BJT and calculate its input/output resistance if the bias current is set at 1mA.
Think about the bias current and how it relates to the output current.
