Degradation of AC signals as inputs of inverter amplifier circuit
You're railing your op-amp.

Basically, the output can't swing to the power rails. As such, even though your circuit has a gain of 100, the maximum voltage you could ever reasonably expect to get out of the output would be +-15V.

Note that this maximum is independent of the gain.

There are basically two things you can do. You can increase your power supply voltages, or decrease your input signal magnitude.



Note that no real op-amp can ever swing completely to the rails. A modern rail-rail output op-amp may swing to a few millivolts of the rails.

However, you're using the ancient (and extremely crappy) 741 op amp. This is not a rail-rail op-amp. From the 741 datasheet:


  VS = ±15V
  RL ≥ 10 kΩ
  Min: ±12v
  Typ: ±14v


You can see with ±15V rails, and a 10 kΩ load on the output (what you have), the output swing is typically +14V - -14V, with a worst-case situation being ±12v.

So basically, your circuit is doing exactly what you would expect, given the op-amp you are using.
