Abstract
A voltage or current generator has a configurable temperature coefficient and includes a first voltage generator that generates a first voltage having a first negative temperature coefficient. A second voltage generator generates a second voltage having a second negative temperature coefficient different to the first negative temperature coefficient. A circuit generates an output level based on the difference between the first voltage scaled by a first scale factor and the second voltage scaled by a second scale factor.
