A self-biased, buffered reference

Voltage reference circuits are common to precision analog designs, in a wide variety of forms. They can be either two or three terminal in basic configuration, and may or may not also provide buffering against line and/or load immunity. Micropower analog circuits are growing in both fashion as well as performance, ...
