Abstract
A method for calculating a calibration gain used for common-mode rejection in a current sensing system may include measuring a first value of a common-mode voltage associated with the current sensing system and a first output value of the current sensing system occurring at the first value of the common-mode voltage, measuring a second value of the common-mode voltage associated with the current sensing system and a second output value of the current sensing system occurring at the second value of the common-mode voltage, and based on a difference between the second output value of the current sensing system and the first output value of the current sensing system and a difference between the second value of the common-mode voltage and the first value of the common-mode voltage, calculating the calibration gain.
