-Design an amplifier to achieve a gain of 16 ±10%.Choose an Rf > 2[k], again in order to meet ideal op-ampassumptions. With reference to Figure , record your resistanceshere.
- With an input voltage large enough to be convenient,yet small enough so that the amplifier output is not saturated,view the input voltage vG and the output voltage vOUT on theoscilloscope and sketch them on graph paper. Measure vG, thevoltage at the non-inverting input v+, the voltage at the invertinginput v-, and vOUT, and record these values in The table below. Calculate the measured gain and enter it along with thepercent error. Indicate appropriate units.
