5 cards from this section. Quick, good the night before a test.
What does a current amplifier do?
Think about the focus on 'current' instead of 'voltage'.
What is the formula for calculating output current?
Look at the terms we discussed for output and input.
What is the main function of a current amplifier?
Think about what differentiates it from voltage amplifiers.
True or False: Coupling capacitors allow both AC and DC to pass.
Recall their protective function in amplifier circuits.
You have a current amplifier with an unloaded gain of 15 and an input current of 1.5mA. If connected to a 1kΩ load, calculate the output current. Consider the load's effect.
Calculate how much of the output current flows through the load versus what is available internally.
Design a current amplifier circuit that takes a 1mA input and delivers a 10mA output to a resistive load. Specify the components involved.
Consider how to ensure the biasing maintains proper current flows.
