Abstract
Due to their physical operating principle, resistive gas sensors demand for very widerange interface circuits. As a consequence, the design of read–out devices, with particular emphasis on integrated circuit solutions, has to face off several limitations, like noise contribution and limited voltage supply. The combination of these constrains would lead, in a traditional linear design approach with digital output, to the exploitation of conditioning network circuits and A/D converters with unreliable specifications. This situation is described in the following to define the fundamental limitations. Moreover a design optimization technique for a state–of–the art solution is reported.
