Abstract
Exemplary implementations include dynamically compensating a system voltage by determining an actual load current based on a sense voltage across a sense resistor and a resistance of the sense resistor, the sense resistor being operatively coupled to a system node, generating a gain current based on the actual load current and a predetermined load current, determining a gain voltage based on a system gain and the gain current, and generating a compensation voltage based on a predetermined system voltage at a system node, an actual system voltage at the system node, and the gain voltage. Exemplary implementations also include calibrating a dynamic voltage compensation device by applying a predetermined voltage to a system node operatively coupled to the system load, a sense resistor, and an internal system node, determining a test current based on a sense voltage across the sense resistor and a resistance of the sense resistor, determining a system resistance based on the predetermined voltage, the test current, and an internal system voltage at the internal system node, and setting a system gain based on the system resistance at a gain block device.
