The input reference is the 0.6V source connected to R5.Neither input is ground-referenced, so I don't see how the voltage at either input can be calculated.
I'm assuming that Voffset1 is modeling the offset voltage of the opamp (that you are ignoring)?Could anyone here confirm what will be the voltage at pin 3 of op amp for below schematic in terms of mathematical equation. I want to proof read my equation if its correct or not. my final equation is 0.6V+{(R7/R5)*I1*R4} ignoring offset voltage of opamp.
Thanks in advance
