Abstract:
1. A resistor with temperature coefficient of resistance (TCR) compensation, the resistor comprising: a resistive strip disposed between first and second conductive strips; a first main terminal and a first voltage sense terminal formed in the first conductive strip; a second main terminal and a second voltage sense terminal formed in the second conductive strip; a first rough TCR calibration slot located between the first voltage sense terminal and the first main terminal, the first rough TCR calibration slot having an opening facing away from the resistive strip, and a depth that extends toward the resistive strip; a second rough TCR calibration slot located between the second voltage sense terminal and the second main terminal, the second rough TC calibration slot having an opening facing away from the resistive strip, and a depth that extends toward the resistive strip; and a fine TCR calibration slot formed between the first and second voltage sense terminals.
