- I could not retrieve the posting you suggested. Google wouldn't find
it, no matter what I tried.
- I have to believe my SPICE is drunk, since every time I try to use a
Vbe multiplier or different transistors, distortion rises from -60/-80
dB to some like -40...
- Yes, I'm not familiar at all with IC design.
Could you design/produce a couple of IC's for me for free, so I can
better undertand the process?
