Journal ArticleDOI
A Ratiometric Readout Circuit for Thermal-Conductivity-Based Resistive CO 2 Sensors
Zeyu Cai,Robert van Veldhoven,Annelies Falepin,Hilco Suy,Eric Sterckx,Christian Bitterlich,Kofi A. A. Makinwa,Michiel A. P. Pertijs +7 more
TL;DR: A readout circuit for a resistive CO2 sensor, which operates by measuring the CO2-dependent thermal conductivity of air, using dynamically-swapped transducer pairs to cancel their baseline-resistance, so as to relax the required dynamic range of the ADC.
Journal ArticleDOI
A Phase-Domain Readout Circuit for a CMOS-Compatible Hot-Wire CO 2 Sensor
Zeyu Cai,Robert van Veldhoven,Hilco Suy,Ger de Graaf,Kofi A. A. Makinwa,Michiel A. P. Pertijs +5 more
TL;DR: A readout circuit for a carbon dioxide (CO2) sensor that measures the CO-dependent thermal time constant of a hot-wire transducer and uses a phase-domain modulator to digitize the phase shift of the resulting temperature transients.
Proceedings ArticleDOI
An integrated carbon dioxide sensor based on ratiometric thermal-conductivity measurement
Zeyu Cai,R.H.M. van Veldhoven,Annelies Falepin,Hilco Suy,Eric Sterckx,Kofi A. A. Makinwa,Michiel A. P. Pertijs +6 more
TL;DR: In this paper, a CO 2 sensor intended for indoor air quality sensing is presented, which achieves a resolution of 228ppm (1σ) in a 70s measurement time, while consuming 11.2mW from a 1.8V supply.
Journal ArticleDOI
A CMOS Readout Circuit for Resistive Transducers Based on Algorithmic Resistance and Power Measurement
Zeyu Cai,Luis E. Rueda Guerrero,Alexander Mattheus Robert Louwerse,Hilco Suy,Robert van Veldhoven,Kofi A. A. Makinwa,Michiel A. P. Pertijs +6 more
TL;DR: In this article, a front-end circuit, integrated in a standard CMOS technology, sets the voltage drop across the transducer, and senses the resulting current via an on-chip reference resistor.

Sensor arrangement and method for generating measurement signals
Hilco Suy,Dimitri Soccol +1 more
TL;DR: In this article, a sensor arrangement consisting of a capacitive sensor (11) with a first electrode line (12), a second, a second and the third electrode lines (16, 16, 20) and a sensitive layer (30) arranged at the first, the second, the third and the fourth electrode lines is presented.
