Beschreibung
Zusammenfassung:	A current sense resistor and a method of manufacturing a current sensing resistor with temperature coefficient of resistance (TCR) compensation is disclosed. The resistor has a resistive strip disposed between two conductive strips. A pair of main terminals and a pair of voltage sense terminals are formed in the conductive strips. A pair of rough TCR calibration slots are located between the main terminals and the voltage sense terminals, each of the rough TCR calibration slots have a depth selected to obtain a negative starting TCR value observed at the voltage sense terminals. A fine TCR calibration slot is formed between the pair of voltage sense terminals. The fine TCR calibration slot has a depth selected to obtain a TCR value observed at the voltage sense terminals that approaches zero. The resistance calibration slot has a depth selected to calibrate a resistance value of the resistor.
