Original, or pure stupid? :D

JS:
Only TI could build a TI voltage reference using 10000 TI's voltage references.  :horse:

I once build an 100V reference(with 10V output as well) by stacking 10 LT1021BCN8-10 plus a constant current source. This IC is much better in term of drift and noise.

I also had a plan to stack 14 LTZ1000 to obtain a super 100V. For this purpose, I have selected 14 LT1000 that added up to exact 100.000V. The 14 power supplies have to be isolated.

I'd love to see this approach applied to the 100kV version :-DD
