Thermistor with tunable resistance

Abstract:

A device having a first terminal region and a second terminal region. The first terminal region includes fine-tune (FT) metal stripes that are separated from each other by a first distance along the longitudinal direction. The second terminal region is spaced apart from the first terminal region by at least an inter-terminal distance. The second terminal region includes coarse-tune (CT) metal stripes that are separated from each other by a second distance along the longitudinal direction. The second distance is greater than the first distance, and the inter-terminal distance greater than the second distance. Each of the FT metal stripes may be selected as a first access location, and each of the CT metal stripes may be selected as a second access location. A pair of selected first and second access locations access a sheet resistance defined by a distance therebetween.
