A bandgap voltage reference is a temperature independent voltage reference circuit widely used in integrated circuits. It produces a fixed (constant) voltage regardless of power supply variations, temperature changes, or circuit loading from a device. It commonly has an output voltage around 1.25 V (close … See more The voltage difference between two p–n junctions (e.g. diodes), operated at different current densities, is used to generate a current that is proportional to absolute temperature (PTAT) in a resistor. This current is used to … See more • The Design of Band-Gap Reference Circuits: Trials and Tribulations p. 286 – Robert Pease, National Semiconductor • Features and Limitations of CMOS Voltage References • ECE 327: LM317 Bandgap Voltage Reference Example – Brief explanation of … See more • 1966, US Patent 3271660, Reference voltage source, David Hilbiber. • 1971, US Patent 3617859, Electrical regulator apparatus including … See more • Brokaw bandgap reference • LM317 • Silicon bandgap temperature sensor See more http://www.seas.ucla.edu/brweb/papers/Journals/BRSummer16Bandgap.pdf
