1. A current sensing device comprising:
a die; a shunt resistor fabricated onto the die, the shunt resistor for passing the current that is to be sensed, the shunt resistor being fabricated from a first material having a first temperature coefficient, and the shunt resistor having a first node and a second node; a first compensation resistor fabricated onto the die, the first compensation resistor coupled to the first node of the shunt resistor, wherein the first compensation resistor is proximate the shunt resistor and is maintained at approximately the same temperature as the shunt resistor by way of its proximity, and wherein the first compensation resistor has a temperature coefficient that is close to the temperature coefficient of the shunt resistor; and a second compensation resistor fabricated onto the die, the second compensation resistor coupled to the second node of the shunt resistor, wherein the second compensation resistor is proximate the shunt resistor and is maintained at approximately the same temperature as the shunt resistor by way of its proximity, and wherein the second compensation resistor has a temperature coefficient that is close to the temperature coefficient of the shunt resistor. |
