Composite resistors

摘要

A composite resistor includes a thin film resistor element having a first temperature coefficient of resistance and a metal resistor element having a second temperature coefficient of resistance. A portion of the metal resistor element overlaps a portion of the thin film resistor element such that the portion of the metal resistor element is in thermal communication with the portion of the thin film resistor element to compensate for a resistance drift arising during operation of the composite resistor.

1. An electronic device comprising:
a thin film resistor element having a first temperature coefficient of resistance (TCR); a metal resistor element having a second TCR of opposite sign to the first TCR, the metal resistor electrically connected with the thin film resistor; an insulating material interposed between the thin film resistor element and the metal resistor element; an overlapping region comprising a portion of the metal resistor element overlapping a portion of the thin film resistor element such that the portion of the metal resistor element is in thermal communication with the portion of the thin film resistor element through the insulating material.
