Noise measurements on balanced polypyrrole thin-film micro-bridges are presented. The measurements were aimed to study the effects of the exposure to gaseus species on the resistance fluctuation spectral density. The use of balanced structures permits to reduce the effects of d.c. voltage transients and drift on the measured power spectra.

Abstract
Noise measurements on balanced polypyrrole thin-film micro-bridges are presented. The measurements were aimed to study the effects of the exposure to gaseus species on the resistance fluctuation spectral density. The use of balanced structures permits to reduce the effects of d.c. voltage transients and drift on the measured power spectra.File in questo prodotto:
