15.5 Applying buried-zener references
As we saw in Chapter 14, the buried-zener reference is one of the most mature volt-
age reference topologies, and it was designed to meet an extremely high level of pre-
cision. Only in recent years have any of the other topologies come close to matching
some of its outstanding characteristics. The buried-zener product was expensive to
build, characterize, test, and burn in (many products received many hours of burn-in at
