Frequency transducers of gas concentration for the diagnosis of strains of bacteria Helicobacter pylori

Abstract

The above considered mathematical model of an optical-frequency transducer of gas concentration for diagnosing strains of the bacterium Helicobacter pylori takes into account the effect of optical radiation on the channel, source and drain p-n junctions of MOS transistors. Photosensitive field-effect transistors implement the capacitance and inductance of the oscillatory circuit of an optical-frequency gas transducer, which change under the action of optical radiation, and, accordingly, the gas concentration, which made it possible to increase the sensitivity of the gas concentration transducer.
