Abstract:
A current sensor includes a die and a shunt resistor having a first temperature coefficient and having a first node and a second node fabricated onto the die, wherein the shunt resistor is for passing the current that is to be sensed. A first compensation resistor is fabricated onto the die and is coupled to the first node of the shunt resistor, wherein the first compensation resistor is proximate the shunt resistor and has a temperature coefficient that is similar to the temperature coefficient of the shunt resistor. A second compensation resistor is fabricated onto the die and is coupled to the second node of the shunt resistor, wherein the second compensation resistor is proximate the shunt resistor and has a temperature coefficient that is the close to the temperature coefficient of the shunt resistor.
