OpAmp.Plus, OpAmp.Minus, OpAmp.Out nodes

An example (with pst-PSPNodes, pst-circ2 and pst-eucl)

  \begin{pspicture}(10,5)
    \psDefPSPNodes*
    \psset[pst-circ2]{%
      LabelRot=0,capacitor.ShowAutoLabel=false,resistor.LabelOffset=0pt}
    \bgroup
      \psset{linestyle=none}
      \pcline(PSPbl)(PSPtl)\ncput[npos=.6]{\pnode{vE}}
      \pcline(vE)(PSPbr|vE)\ncput[npos=.2]{\pstGeonode[PosAngle=-90]{A}}
        \ncput[npos=.4]{\pnode{vPlus}}\ncput[npos=.7]{\pnode{AO}}
    \egroup
    \capacitor[Label=$C$](vE)(A)
    \capacitor[Label=$C$](A)(vPlus)
    \resistor(A)(A|PSPtl)
    \resistor(vPlus)(vPlus|PSPbl)
    \OpAmp[Style=french+-](AO|PSPcl)
    \pcangle[angleB=180](vPlus)(OpAmp.Plus)
    \pcloop[angleA=180,angleB=0](OpAmp.Minus)(OpAmp.Out)
    \pcangle[angleA=0,angleB=0](A|PSPtl)(OpAmp.Out)
    \ground(vPlus|PSPbl)
    \wire(OpAmp.Out)(PSPbr|OpAmp.Out)
    \pcline[nodesep=.1]{->}(PSPbl)(vE)\nbput{$v_e$}
    \ground(PSPbl)
    \pcline[nodesep=.1]{->}(PSPbr)(PSPbr|OpAmp.Out)\naput{$v_s$}
    \ground(PSPbr)
  \end{pspicture}

For your specific needs, I'll have a look this WE.
