An ideal three-input inverting summing amplifier is to be designed. The input voltages are \(v_{I 1}=2+2 \sin \omega t \mathrm{~V}, v_{I 2}=0.5 \sin \omega t \mathrm{~V}\), and \(v_{I 3}=-4 \mathrm{~V}\). The desired output voltage is \(v_{O}=-6 \sin \omega t \mathrm{~V}\). The maximum current in any resistor is to be limited to \(120 \mu \mathrm{A}\).
