Realizations of CMOS Smart Temperature Sensors
This chapter describes the realizations of three different CMOS smart temperature sensors that have been designed in the past five years. The first realization finds its application in a tyre monitoring system, where it watches the temperature of the tyre and compensates thermal cross-sensitivities of a pressure sensor. The second realization is a general-purpose ambient temperature sensor, where special attention has been paid to high uncalibrated accuracy. The last version can measure the temperature of a remote bipolar transistor and has its application in microprocessor thermal management.
