CMOS bandgap references and temperature sensors and their applications
Analysis and Design of Bandgap Reference (BGR) | SpringerLink
Voltage references and linear voltage regulators have much in common. In fact, the latter could be functionally described as a reference circuit, but at a greater current or power output level. Accordingly, many of the specifications of the two circuit types have great commonality even though the output voltage tolerance of references is usually tighter with regard to temperature drift, accuracy, etc. Voltage references have a major impact on the performance and accuracy of analog systems. Both high initial accuracy and calibration are likely to be necessary in a system making absolute bit measurements. Note that many systems make relative or ratiometric measurements rather than absolute ones. In such cases the absolute accuracy of the reference is not as important, although noise and short-term stability may be.
