Abstract
A linear temperature sensor that incorporates passive bipolar semiconductor devices and is capable of high accuracy over a very wide temperature range. The passive bipolar semiconductor device splits a voltage drop between the bipolar semiconductor and a resistor, such that the voltage drop varies approximately linearly in negative dependence on temperature. Optionally the linearity may be improved by providing sufficient current to produce a self-heating effect which compensates for non-linear deviations in performance at low temperatures.
