Electronic – Learning about voltage references


I want to study the bandgap voltage reference and use it in somewhere. But first I would like to learn more about the basics of generating and using voltage references (mostly for operational amplifiers). What course of studies should I take?

I have worked on operational amplifiers, but I have usually used a ready-made reference from different lab devices. It is the first time I have encountered a situation where I want to add a voltage reference of my own. What kind of things should I study and what should be the approach to learn about this stuff?

Bob Widlar invented the first bandgap reference in 1971, and Bob Pease wrote a pretty thorough column summarizing how they work.

If you look up on google "bandgap references" or "bandgap references widlar" you'll get a ton of relevant links. Here are a few:
