Abstract
In one aspect of the invention, a semiconductor die includes a plurality of resistive elements operable to receive a voltage differential between at least two of the resistive elements. The semiconductor die also includes a test circuit coupled to at least three tap points along the resistive elements. The test circuit is operable to measure a voltage at at least two of the tap points. A difference in the voltages between the at least two tap points is proportional to a resistance of the one or more resistive elements between the at least two tap points.
