Sigma-delta processing in multisensor systems for carbon monoxide detection

This paper presents a circuit to measure carbon monoxide concentration. Signals from three sensors are combined using sigma-delta processing to compensate for relative humidity and interfering gases. Appropriate circuit techniques are used to reduce offset and flicker noise in MOS amplifiers.
