I am working on a homework assignment for an Electronics class and I am to design a two stage op amp with a gain of A=A1*A2=-X. X equals a group member's student ID which in our case totaled to 39. Our resistor values are 130k/20k=6.5, and 120k/20k=6. When I put the schematic into PSPICE and run a simulation I am getting a DC voltage at the amp outputs which is not making sense to us, and I have shown the schematic to other students, and a T.A. and the schematic looks okay to us but none can figure out why the outputs are showing a DC voltage. I have recreated the schematic a dozen times trying to switch terminals and mess around with the battery sources but I always get a similar output.
Any advice is greatly appreciated.
Thank you.
