Abstract
Current sensing circuitry for sensing a current through a load comprises an adaptive-resistance sensor component arranged to be operably coupled in series with the load, and control logic for controlling a resistance of the adaptive-resistance sensor component. The control logic is arranged to receive a signal representative of a voltage across the adaptive-resistance sensor component, compare the received signal to a reference value that is representative of a determined voltage, and in response to the comparison control the resistance of the adaptive-resistance sensor component, such that the voltage across the adaptive-resistance sensor component substantially tracks the determined voltage value.
