Abstract
A voltage reference generator which can be automatically calibrated has a first mode and a second mode. The voltage reference generator provides a bandgap reference voltage with a voltage reference node having a capacitance. Calibration logic, which can be on the same integrated circuit device as the voltage reference generator, executes a calibration sequence including enabling the voltage reference generator in the first mode to produce a voltage on the voltage reference node, holding the voltage by the capacitance, and then enabling the voltage reference generator in the second mode and calibrating the voltage reference generator in the second mode relative to the voltage held on the voltage reference node, to provide the bandgap reference voltage.
