| May 31, 2016 at 9:34 | comment | added | stefandz | Pretty sure that the TL081 issue is the fact that it is the default opamp selected when drawing schematics in CircuitLab - just popped into my head the other day. I think the OP is using it to represent an opamp in the original schematic - not necessarily a TL081. | |

| May 25, 2016 at 14:13 | comment | added | user16324 | It's there to balance out the input bias currents. Read any intro to opamps or search "opamp input bias currents" for more information. What it's doing in this circuit, only its designer knows : the TL081 has substantially zero bias current... | |
