readout circuit forms the necessary ingredients of a new generation of electronic nose (e-nose) devices that, owing to their form factor and power consumption, enable a range of novel applications. Using “application specific” polymer coatings, the individual resonators can be tuned to detect mixtures of volatile organic compounds (VOCs) with a broad range of applications such as: personalized health and environmental air quality measurements leading to more energy efficient sustainable buildings. Main research directions in VOC detection system include high-power thermo-mechanically actuated sensors and low-noise differential readouts [1] or Pierce-based oscillators of [2] suited for low motional sensor impedance. This paper presents a hybrid low-power, high-resolution enose system, including the necessa
