3 cards from this section. Quick, good the night before a test.
What is the purpose of a current amplifier?
Think about applications where current needs to be enhanced.
Define DC blocking capacitor.
Consider its function in an amplifier.
What is the main function of a current amplifier?
Focus on the definition of what these amplifiers do.
True or False: A DC blocking capacitor allows both DC and AC signals to pass.
Consider the purpose of such capacitors within a circuit.
Design a simple current amplifier circuit that operates effectively for a given input current of 1.5 mA with an unloaded gain of 12. Discuss the anticipated loading effects.
Consider how the performance would change with loading attached.
Consider a scenario where a current amplifier experiences significant load resistance at the output, significantly affecting its output current. Discuss how to modify your circuit to maintain desired output levels despite loading.
What resistor values can you adjust to counteract loading?
