Precision Temperature Sensors in CMOS Technology
Author: M. Pertijs, Delft University of Technology, The Netherlands
Advisor: Prof. J.H. Huijsing
This thesis describes the analysis and design of precision temperature sensors in CMOS technology. It focuses on so-called 'smart' temperature sensors, which provide a readily interpretable digital output. Over the military temperature range, which extends from - 55 0C to + 125 0C, the inaccuracy obtainede using such sensors in previous work was about +-2 0C. In this work, that inaccuracy is reduced to +-0.1 0C, so that the performance of CMOS temperature sensors becomes comparable to that of conventional sensors such as platinum resistors and thermistors. To keep productions costs low, a standard CMOS process is used, and the sensors are calibrated at only one temperature.
Identifiers: CMOS temperature sensors, analog-to-digital converter (ADC), smart temperature sensors
