ABSTRACT:
The present invention involves adding additional structures to a polysilicon resistor which do not significantly affect the resistance of the polysilicon resistor. These additional structures add to the area of the polysilicon resistor, and therefore reduce the self-induced temperature change caused by the voltage across the resistor. Since the resistance of the polysilicon resistor depends on its temperature, the reduction of the self-induced temperature change lowers the variation in the resistance value at different voltages.
