Design for thermal stability?

[Bricolo]

Hi,

I'm looking for information about how to design analog circuits that don't vary much with temperature. I mean things like bias currents, dc offset...

You'll certainly guess what this is about: DC coupled output, and the DC offset's drift over temperature

So, how can low temperature coefficients be achieved? I assume that current sources and/or voltage references need special care to have a zero tempco (or to have the same tempco, in symmetrical topologies) but that may not be the only requirement; and I also don't know how to design zero (or low) tempco CCS or Vrefs


Feel free to give some input
