a) Design a noninverting amplifier with a gain of 6. Assume the Op-amp is ideal and start with the Op-amp circuit below. b) Suppose we wish to amplify a voltage vg, such that 1.5V vg -1.5V, what are the smallest power supply voltages that could be used with the resistors selected in part (a) and still have the Op-amp in this design remain in its linear operating region?
