Abstract:
1. A resistive circuit, comprising: a first terminal and a second terminal; first and second resistive segments coupled between the first and second terminals, wherein the first and second resistive segments have resistances that vary non-linearly with applied voltage; and a third terminal A electrically coupled to the first resistive segment such that substantially no DC current flows in the third terminal A, and a third terminal B electrically coupled to the second resistive segment such that substantially no DC current flows in the third terminal B, wherein the third terminal A has a first voltage with respect to the first terminal and wherein the third terminal B has a second voltage with respect to the second terminal, and wherein the third terminal A is disposed physically proximate to the first resistive segment and the third terminal B is disposed physically proximate the second resistive segment such that non-linearity of resistance of the first resistive segment at least partially compensates for non-linearity of resistance of the second resistive segment.
