Devices Model Research Technique of Analogous Front-End for Optical Sensors

Abstract

In our paper the aim is to adapt the methods of mathematical SPICE modeling to the problems of impedance spectroscopy and to develop new approaches for increasing the efficiency of the research of impedance type signal converters. This approach based on non-harmonic, mainly pulsed signals in the form of a meander for structural simplification and expansion of the frequencies spectrum. This approach can be used for express high-sensitivity and selective detection of biological substances for diagnostic purposes by means of optical sensors.
