Abstract
The output of a smart temperature sensor is a digital representation of its temperature. This requires a ratiometric temperature measurement: the ratio of a temperature-dependent voltage and a reference voltage is determined using an analog-to-digital converter. This chapter describes how substrate bipolar transistors in CMOS technology can be used to accurately generate these voltages.
