Abstract
In one embodiment, a method for measuring current comprises generating a sensor current based on a current being measured. The method also comprises converting a combined current into a first frequency, wherein the combined current is a sum of the sensor current and a common-mode current, and converting the first frequency into a first count value. The method further comprises converting the common-mode current into a second frequency, converting the second frequency into a second count value, and subtracting the second count value from the first count value to obtain a current reading.
