5 cards from this section. Quick, good the night before a test.
Define an inverting amplifier.
Think about the phase relationship.
What is the formula for the gain of a non-inverting amplifier?
Consider how the resistors affect the gain.
What is the gain of an inverting amplifier when R_f is 10kΩ and R_{in} is 1kΩ?
Remember the formula for inverting gain.
Is a non-inverting amplifier output in phase with its input? (True/False)
Think about the operational characteristics of non-inverting amplifiers.
Calculate the output voltage of an inverting amplifier with R_f = 20kΩ and R_{in} = 2kΩ when the input voltage is 3V.
Remember to first find the gain using the resistors.
Design a circuit with a non-inverting amplifier with a gain of 5. If R_1 = 1kΩ, what should R_f be?
Use the gain formula to find R_f once you know A_v.
