Abstract
A calibration process determines a desired supply voltage for operating an electronic device. During the calibration process automatic test equipment controls a power supply to sweep the supply voltage to the electronic device across a predefined voltage range while monitoring a performance characteristic of the electronic device. The automatic test equipment determines the desired operating voltage based on a minimum supply voltage at which the monitored performance characteristic meets a minimum acceptable performance standard and stores the desired operating voltage to a non-volatile storage. During a startup sequence, the electronic device controls the power supply to provide the desired operating voltage as the supply voltage to the electronic device.
