Question

Design an inverting amplifier with a gain of 6. Use an ideal op amp, a 20k Ω resistor in the feedback path, and 15 V power supplies.

Answer 1

To design an inverting amplifier with a gain of 6, you can use a 20k Ω resistor in the feedback path and set the input resistor (Rin) to 3.33k Ω.

Step-by-step explanation:

To design an inverting amplifier with a gain of 6, we can use the formula:

Vout = -Vin * (Rf / Rin)

In this case, the resistor in the feedback path (Rf) is given as 20k Ω. To achieve a gain of 6, we can set Rin to a value of 3.33k Ω. We can then connect the input signal to the inverting terminal of the op amp and connect Rf in the feedback path.
