I’ve been asked to create a sawtooth wave form with four input voltages. After doing this I then added a second op-amp to both change the range of the wave form from -/+5v to -/+2.5 and DC offset of 2.5v to create a wave form that ranges from 0v – 5v as required by the question. For the most part I think I’m close enough with my result apart from the second op-amp seems to of “flipped” the wave form and I can’t quite figure out why and how to solve the issue.
I've included a picture of my circuit, wave form after the first op-amp and after the second op-amp.
Any help would be appreciatedhttps://www.physicsforums.com/attachments/286448https://www.physicsforums.com/attachments/286449https://www.physicsforums.com/attachments/286450
