Prokopova M. Microelectronic frequency transducers of concentration of gas

The subject of the research - a process of the transformation to concentrations of the gas in frequency signal in sensitive transistor structure; the purpose of the research - an improvement metrological and economic factors of the transducers to concentrations of the gas; the methods of the research - an equations mathematical physicists, positions to theories to functions complex variable, theories of the calculation of the nonlinear electric circuits with use the laws Kirhgofa, theories to probability, differential and integral calculation; theoretical and practical results - frequency microelectronic transducers to concentrations of the gas on base two bipolar and MOSFET- and bipolar transistor structures with negative resistance with passive and active inductive element, mathematical models, analytical expressions and software for modeling and calculation of the features designed microelectronic frequency transducers to concentrations of the gas; the degree of the introduction - within branch; the enterprise of the use - a systems of the measurement to concentrations of the gas.
