Frequently an amplifier with power gain but no voltage gain isrequired. This can be accomplished using the configuration ofFigure 6, but with Rf =0 and Ri left open, i.e., Ri equal toinfinity. In this case, the gain is extremely close to 1.
-Set up a unity gain amplifier, repeat the voltage measurementsof the preceding section, and record them below.

Figure 6. The Non-inverting Op-Amp Configuration. Note that even in the non-inverting case, negative feedback is used. The gain is Av=vGvOUT=1+RiRf.
