Yeah, indeed, very complex, two opamps and for a dollar worth of resistors. You are right, very heavy analog voodoo stuff. Is the modern EE afraid of everything more then one part ( most times named atmel or pic) ? They make the most simple things with an overload of digital stuff but two opamps and some resistors is heavy. I'm afraid f the future of anlog design. It takes me more time to type this than to build it.
But i'm just ranting ;-)
All depends on what the topic starter wants to do. If he just wants 1V and not much accuracy he can use two resistors. If he wants to make a moderate accurate Vref he can use one TL and one sinple opamp and less then 10 resistors. If he wants to make 1.000,000V he just has to forget t for now
And there are many more options
