Abstract
Current measurement device and methods are provided. An output signal is provided based on a voltage across a resistive element. A correction circuit is configured to estimate an indication of a temperature change of the resistive element based on the voltage across the resistive element and to correct the output of the current measurement device based on the indication of the temperature change and a measured temperature.
