A Micromachined Low-Power
Temperature-Regulated Bandgap Voltage Reference
by
Richard J. Reay, Erno H. Klaassen, and Gregory T. A. Kovacs

Abstract—A low-power, temperature-regulated bandgap voltage
reference is demonstrated in a commercial CMOS process.
Low-power operation is achieved by thermally isolating a small
portion of the die using a single postprocess micromachining step
requiring no extra masks or modifications to the CMOS process.
The reference has a 53 000 C/W thermal resistance, a 2.5 ms
thermal time constant, and uses 1.5 mW at 25C. Temperature
regulation improves the temperature coefficient from 400 ppm/C
to 9 ppm/C over 0–80C.
