In accordance with the present disclosure current sensing methods, apparatuses and arrangements are disclosed. The arrangement can include a sense element to convey a current from a source to a load and a compensation element can be located proximate to the sense element. The compensation element can have a resistance that changes proportional to a change in temperature of the sense element. The arrangement can further include an operational amplifier having a first input connected to the sense element, a second input connected to the compensation element and an output that provides an output signal that biases a current through the compensation element in response to a voltage across the sense element. The bias current can provide an output signal proportional to the conveyed current and the compensation element can provide temperature compensation for the output signal.
