Positive voltage on the p type anode blue drives holes toward the. It produces a fixed constant voltage regardless of power supply variations temperature changes and circuit loading from a device. 4 how to make a bandgap voltage reference in one easy lesson let me begin with a sort of hand waving description of pn junctions and bipolar transistors.
This representation of a pn junction is shown forward biased.
This representation of a pn junction is shown forward biased. This simple robust idea provides a temperature indepen dent ti voltage and a proportional to absolute temperature ptat current. 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 and circuit loading from a device.
