Hi jordan76,
The first three lines define the simulation circuit topology as shown in the figure. The circuit definition for the op amp is not shown here.
Both voltage sources V1 and V2 have a DC value of 0V and AC value of 1V.
The ".AC" statement is a hspice analysis statement. It takes several forms, one of which is as follws:
.AC DEC 10 100 1MEG
This statement will do frequency analysis (AC analysis) from 100Hz to 1 Meg-Hz, taking 10 frequency points for every decade.
