Very high resistence

[Esteban]

Hi everybody,
I just wonder, is it possible adjust resistance of that transistor network?
Let say instead 100G just 1G.
Regards.

See in Google patents # 5760450 Semiconductor resistor using back-to-back zener diodes

Thanks Esteban!
I have downloaded that suggested patent. I need time to deep inside to understand that.
