It is possible (but maybe unlikely) that 'mliccione89' does not need this TIA to be linear.? Maybe all she/he wants to do, is to detect and observe pulses, in which case it might be OK that it is nonlinear.? If so,?then maybe it is OK to use the power supply voltages and the closed-loop gain that were used in the original schematic, where the amp is driven into saturation, and where the fact that it would oscillate doesn't matter when it's in saturation.? But if that were the case, I also want to suggest that the simulation might not be as accurate as you desire.? And maybe it's a waste of a good op-amp that is not being used as an op-amp.
