DIGITALLY CALIBRATED VOLTAGE REGULATORS FOR POWER MANAGEMENT

摘要

A computer provides a graphical user interface for displaying a virtual representation of a voltage regulator and for accepting a user requirement for the voltage regulator. The computer automatically determines an internal calibration setting of the voltage regulator that meets the user requirement. The computer simulates operation of the voltage regulator as calibrated with the internal calibration setting. The internal calibration setting is downloaded to the voltage regulator. A calibration controller of the voltage regulator receives the internal calibration setting and outputs digital calibration bits in accordance with the internal calibration setting. The digital calibration bits works in conjunction with interface circuits to adjust circuits of a voltage regulator core to digitally calibrate the voltage regulator.
