4 cards from this section. Quick, good the night before a test.
What is the purpose of a voltage amplifier?
Think about how amplifiers interact with voltage signals.
Define current amplifier.
What key feature defines current amplification?
What does a current amplifier primarily do?
Focus on what type of signal it works with.
True or False: A coupling capacitor allows DC signals to pass while blocking AC.
Recall the function of a coupling capacitor.
Design a cascaded amplifier system where a voltage amplifier feeds into a current amplifier. Specify the expected output given an input voltage and the gains of each stage.
Consider how the output signal from one stage serves as the input to the next stage.
In a given transimpedance amplifier, the input current is 2mA and the transimpedance gain is 200 ohms. Calculate the output voltage while considering load effects.
Utilize the transimpedance formula I_in * Z to derive the output voltage.
