Feedback Topologies and Closed-Loop I/O Resistances 7.11 (a) Given that with vi 5 10.0 mV the series-shunt confi guration of yields vf 5 9.5 mV and vo 5 5.0 V, fi nd the values (and units) of a, b, L, and A (use two methods to calculate A). (b) If gain a drops to 50% of the value found above, how are vf and vo affected? Cross check! (c) Repeat part (a), but for the series-series confi guration of  assuming the same situation at the summing side, but io 5 5.0 mA at the sensing side. (d) If a doubles, how are vf and io affected? Cross check!
