Temperature Compensated Exp Conv.

[Tadej Bozicko]

Hi all!
 
After a week of restles work in SPICE simulator, I've came up with a new compensation circuit for CA3046 based expo converters. As it shows simulator, the circuit totally cancel out the temperature dependance of expo converter. Too good to be true? Oh, yes... the bad thing: the circuit had not been built yet, as I am on short with my spare time. Anyone willing to give it a shot, to see, how it behaves in real life before I do? 
Oh, yes... the circuit:

Any comments, critics, flames greatly recommended!

P.S: Excuse my poor english!
