Abstract: Methods and systems for operating a voltage regulator are described. An apparatus may receive a feedback signal from a power stage. The feedback signal may be one of a sensed signal measured from an output of the power stage and a calibration signal representing a fixed voltage. The apparatus may convert the feedback signal into a correction signal. The apparatus may further adjust a synthetic current using the correction signal, the synthetic current being associated with the power stage.
