6.1. [12.5 points] Find the complete and detailed steps to express vo in terms of vs in the non-ideal amplifier circuit shown in Figure 4.6.2. [7.5 points] Based on your expression for vo derived in 6.1. , identify the three conditions that characterize an ideal operation amplifier. Note that, under the fulfillment of the three conditions, the expression for vo should reduce to the formula for the ideal inverting operational amplifier introduced in class: vo = −Rf Rs vs. Figure 4. Circuit schematic for Problem 6.
