Hi all,

I'm quite unsure if I got how it works. 

I just don't see how that arrangement realizes a temperature dependant
scale factor (gain). I can only imagine that this is doing some detuning in
order to roughly compensate for the expected drift.

I find the explanations on the FAQ page confusing, tempcos must be
proportional to T in order to compensate for 1/T since that cancels out
when you multiply. 

Oh, just in case anyone is still confused about tempcos. Check out:

Bye,
 René
