Claim 11:
12. A system comprising: first circuitry arranged to determine a first error between a bandgap reference output voltage of a bandgap reference circuit at a first temperature and a target voltage; second circuitry arranged to measure a second temperature of the bandgap reference circuit; third circuitry arranged to predict the bandgap reference output voltage of the bandgap reference circuit at the second temperature and based on the first error; fourth circuitry arranged to determine a second error between the predicted bandgap reference output voltage and the target voltage; fifth circuitry arranged to determine a trim parameter of the bandgap reference circuit based on the second error; and sixth circuitry arranged to set the bandgap reference circuit with the trim parameter, wherein a third error between the bandgap reference output voltage of the bandgap reference with the trim parameter is less than the second error.
