IntroductionThis report describes the use of the LT-Spice program, and its use as a problem solver using opamps.Procedure Open LT-Spice Create a new schematic Add circuit elements such that the circuit created resembles problem 4.45 ( Figure 1) Develop circuit so that Vo = -2V1 4V2 ( Figure 2) Using DC analysis check that your circuit produced required voltage

Results

Discussion and ConclusionThe results from this lab were very promising. At the end of this lab I had a greater understanding of how I can use the program LT-Spice for checking opamp circuits. As you can see from the results the Vo does not exactly equal -40 but it is only off by .0028. This value is small enough to ignore.
