Temperature Compensated Exp Conv.

[Jim Patchell]

    The one question I have is in your simulation, did you also simulate
any thermal drift the the two J-FET's in the circuit might contribute?
The idea you have is sound.  Thanks for posting this.  I wish I had the
time to try it (must be some sort of epidemic disease going around
eating up free time).
