Abstract
According to one exemplary embodiment, a power gauge for accurately measuring current consumed by a load coupled to a power source includes a current sense resistor having a first terminal coupled to the power source and a second terminal coupled to the load. The power gauge further includes a first integrator configured to integrate a voltage at the first terminal of the current sense resistor during a time period and to output a first integrated voltage. The power gauge further includes a second integrator configured to integrate a voltage at the second terminal of the current sense resistor during the time period and to output a second integrated voltage. A difference between the first and second integrated voltages can be used to accurately determine the current consumed by the load during the time period.
