Final answer:

To design an inverting amplifier with a gain of 6, use an ideal op amp with a 20kΩ resistor in the feedback path. The input resistor should be 3.33kΩ.

Step-by-step explanation:

To design an inverting amplifier with a gain of 6, we can use an ideal op amp with a 20kΩ resistor in the feedback path. The input signal is connected to the inverting terminal of the op amp, and the output is taken from the op amp's output terminal.

In this circuit, the gain (A) is determined by the ratio of the feedback resistor (Rf) to the input resistor (Rin). Since the desired gain is 6, we can set Rf = 6*Rin. Given that Rf = 20kΩ, we can calculate the value of Rin as Rin = Rf/6 = 20kΩ/6 = 3.33kΩ.
