Prelab- A. Analyze the circuit in Figure 4.6 (a) Find V, as a function of R and 1, (assume the op-amp is ideal) (b) If ,-250A and the desired V-0.75V, find the proper value for R. (c) Verify your result by running a SPICE simulation using the 741 up-amp model. Be sure to display voltages on your schematic. (SPICE hint: Most students have found the "Universal Op Amp works best as your op-amp. Pay special attention to your pins as well as the directions of applied voltages. Use separate DC voltage sources which have been grounded for pin 7 and pin 4.) Figure 4.6--Current to voltage converter using an op-amp B. For the circuit in Figure 4.7, calculate V. Calculate the threshold input voltage, V, that will change the output of the comparator from high to low. Show all calculations and explain your work. C. Model the circuit in Figure 4.7 in SPICE for V.2V and V-4V.
