High temperature bandgap reference in PDSOI CMOS with operating temperature up to 300°C

Abstract

This paper describes a bandgap reference with temperature range up to 300°C. Fabricated in a PDSOI CMOS technology, the bandgap reference achieves a box model temperature coefficient of 138ppm from 25 to 300°C, and line regulation less than 1.5mv/V. The minimum operating voltage is 2V and consumes merely 285μW at room temperature over several samples.
