The measurement of carbon-dioxide (CO2) concentration is very important in home and building automation, e.g. to control ventilation in energy-efficient buildings. This application requires compact, low-cost sensors that can measure CO<sub>2</sub> concentration with a resolution of &lt;200 ppm over a 2500ppm range. Conventional optical (NDIR...

This paper presents a readout circuit for a carbon dioxide (CO&amp;#2082;) sensor that measures the CO&amp;#x2082;-dependent thermal time constant of a hot-wire transducer. The readout circuit periodically heats up the transducer and uses a phase-domain &amp;#x0394; &amp;#x03A3; modulator to digitize the phase shift of the resulting...

This paper reports a readout circuit capable of accurately measuring not only the resistance of a resistive transducer, but also the power dissipated in it, which is a critical parameter in thermal flow sensors or thermal-conductivity sensors. A front-end circuit, integrated in a standard CMOS technology, sets the voltage drop across the...
