A designer, needing to provide a unity-gain buffer, considers the use of the circuit topology shown in Fig. 2.19 on page 84 of the Text. However, the amplifier he has available has an open-loop gain of only 10. What closed-loop gain would the simple circuit produce? His boss suggests that he consider the circuit of Fig 2.16 on page 82 as a solution. As well, she requests that the smallest resistor used be 10 Id). What design would result?
