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
