Abstract
In this work, we present a low-voltage (±0.75 V) low-power (0.7 mW) current mode-based integrated interface for resistive gas sensors. The proposed interface, which includes a grounded resistive sensor, shows the capability of compensation of non-idealities of passive and active components, in particular the voltage offset. The sensitivity value has been set to about 16 mV/KΩ, while theoretical resolution is about 135 Ω, to which corresponds a gas resolution lower than 1.5 ppm.
