Abstract
The results of analysis of the output parameters of small-sized seismic motion sensors based on molecular electronics are presented. These devices feature a molecular-electronic transducer with negative feedback the introduction of which makes it possible to improve the sensor performance (specifically, to broaden the frequency range, reduce the amplitude-frequency characteristic (AFC) unevenness, and reduce the nonlinear distortion factor (NDF) value). The operating principle of these devices is outlined. The basic characteristics such as AFC, NDF, and the inherent noise level are determined experimentally, and the methods of their determination are described. The obtained data are analyzed and compared to the data on similar foreign devices. Principal lines of further research aimed not only at improving the technical characteristics but also at establishing a serial production process are specified.
