Hi all,
I think that was Jürgen if I recall correctly.
However, also remember haveing seen a linearising circuit for the 3080
which employed a 3046. Basically the same circuit as in the BA6110, diodes
driven by a current source. So I guess the same thing could be done to a
13x00 too, just that the diodes are the other way round so the Isource
needs to go to V+ instead of GND.
Cheers,
René
