Abstract
The present disclosure relates to a structure including a first curvature compensation circuit which includes a first set of transistors, and a second curvature compensation circuit which includes a second set of transistors. A voltage reference (VREF) signal output from a bandgap voltage reference core with the second curvature compensation circuit is received as an input to the first curvature compensation circuit.
