The Bandgap Reference

A CirCuit for All SeASonSBehzad Razavi IEEE SOLID-STATE CIRCUITS MAGAZINE Summer 2016 9 SSince its inception in the late 1960s, the Bandgap circuit has served as an essential component in most inte-grated circuits. This simple, robust idea provides a temperature-indepen-dent (TI) voltage and a proportional-to-absolute-temperature (PTAT) current. In this article, we study the principles of Bandgap circuit Brief HistorySemiconductor technology does not directly offer any electric quantity that is nominally independent of the ambi-ent temperature. Thus, temperature independence has generally been envi-sioned in the form of combining two phenomena that have opposite tem-perature coefficients (TCs).

resistor and a negative-TC resistor. Applying this idea to voltage quan-tities proved more difficult. It had been long recognized that the voltage across a forward-biased diode has a negative TC (if its bias current does not change much with temperature). However, a positive-TC voltage was missing. In 1964, Hilbiber of Fairchild
