The op amp of Fig. P7.25 is designed to provide V-I conversion with iO 5 vI yR for vI $ 0. The openloop characteristics of the op amp are ri 5 100 kV, ro 5 30 kV, and av 5 104 V/V, and to make up for the relatively high value of ro, we buffer it with a BJT booster, as shown. Using the series-series procedure, estimate Ri , Ro, and the unloaded gain Asc 5 iOyvI at vI 5 1 V if R 5 1.0 kV and the BJT has 0 5 200 and VA 5 50 V.
