Abstract
A temperature sensor (1800) incorporates two diodes (1802, 1804). The voltage difference across each diode is a linear function of temperature. The voltage difference between the two diodes is also a function of the ratio of their respective sizes. These relationships can be used to build a sensor that is inexpensive, reliable, and whose process variance is predictable.
