A simple simulation adapted from the YouTube video by devttys0.

The problem is to invert a 0-20v signal using only an opamp powered by a +/-15V DC supply. The circuit can be broken down to three stages:

  1. Shifting the signal down to be +/-10V signal > Add a 0.1uF cap which will block any DC element in the signal.
  2. Inverting the signal > Use a classic inverting amplifier circuit with two 100k resistors.
  3. Shift the signal up again using a simple voltage divider. This will add back the DC element taken away from the signal.
