Abstract
This paper illustrates a smart sensor system for carbon monoxide detec tion. An innovative technological approach has been pursued to fabrica te gas sensors on silicon substrate, compatible with IC fabrication. A mixed analog-digital electronic interface processes the outputs of th ree sensors to compensate relative humidity and interfering gases. Sig ma-delta signal processing and low-frequency noise reduction technique s are used to minimize silicon area and to meet the required performan ce in a standard CMOS technology.
