• abstract: We have designed and fabricated CMOS preprocessing hardware that successfully thresholds an array of chemical sensor outputs to discriminate among various reducing chemicals. The circuitry uses only 7 transistors per chemical sensor to generate a digital output image that is representative of the reducing chemical present in the sensing environment. The image is generated using the median sensory value in the array as the reference for thresholding. When tested on a heterogeneous array of tin-oxide sensors, this hardware has proven sufficient to discriminate among five major reducing chemicals (acetore, ammonia, carbon monoxide, hexane, and butane).
