An apparatus, method and integrated circuit for broad-range current measurement using variable resistance are disclosed. Embodiments of an apparatus for sensing current through a transistor device may include an interface configured to receive a current from the transistor device for sensing. In an embodiment, the apparatus may also include a sensor component coupled to the interface and configured to receive the current from the transistor device and to generate a responsive sensor voltage, the sensor component comprising an adjustable resistance component, a resistance value of the adjustable resistance component being selectable in response to a level of the current received at the interface.
