Abstract
In some examples, a bandgap reference circuit comprises a first bandgap pair having multiple first diodes and a first resistor positioned between the multiple first diodes. The circuit also comprises a second bandgap pair having multiple second diodes and a second resistor positioned between the multiple second diodes, the second bandgap pair being an inverted form of the first bandgap pair. The circuit further comprises a scaling resistor coupled to the first and second bandgap pairs. The circuit still further comprises an operational amplifier coupled to the first and second bandgap pairs.
