Greetings everyone! I built a "Bubba oscilator" circuit, which is supposed to convert DC signal into AC. (Resource: http://www.hscott.net/bubba.pdf ) The uploaded picture is the exact schematic that I built with only 1 modification. We did not have the TLV2474 ( http://www.ti.com/product/tlv2474 ) so I used 2xTLV272 instead ( http://www.ti.com/product/tlv272 ). When I first tested it the osciloscope showed a perfect sine wave output, but after my initial excitement passed I noticed that the sinewave actually has no negative values. It moves between approximately 200mV and 700mV. My question is: Can the different op amp be the reason for that? Or is there something entirely different I am missing?
PS: I will upload a screenshot of the osciloscope with the exact values about 30 minutes later.
Thank you in advance!
