Re: An analog challenge (and a real problem)

I missed the start of this thread. Are you trying to measure the temperature inside an IC that's performing other functions with a spare junction or just using a junction in an IC as a temperature sensor? If it's just a thermometer why not use one of the temperature measuring ICs such as the LM335 or something newer.
If it's the wire resistance you're worried about, why not either just measure its resistance or calculate it from the gauge and length. Since it's a pure resistance you should be able to compensate for it with a simulated negative resistance (effectively a bucking voltage equal to the current by its resistance).
Of course I might have missed something in your question and I'll just go hide in the corner.
