A bandgap voltage reference is a temperature independent voltage reference circuit widely used in integrated circuits, usually with an output voltage around 1.25 V, close to the theoretical 1.22 eV bandgap of silicon at 0 K. This circuit concept was first published by David Hilbiber in 1964. Bob Widlar, Paul Brokaw and others followed up with other commercially successful versions.
... The voltage difference between two p-n junctions (e.g ... This current is used to generate a voltage in a second resistor ... This voltage in turn is added to the voltage of one of the junctions (or a third one, in some implementations) ...
Famous quotes containing the word reference:
“If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
—William York Tindall (19031981)
