Abstract

Background. Generalization of a variety of ways to implement the method of phase separation of channels, offered by the authors and intended to improve the accuracy of measuring circuits in parametric sensors, will both simplify the process of selection of a way and to synthesize a new way that meets the technical task. The aim of the work is to systematize ways to implement the method of phase separation  of channels. These ways differ by the features of the active inverter output voltage decomposition into components, proportional to the convertible parameters of a sensor’s parametric transmitter.
Materials and methods. Investigations were carried by using the methods of the classical theory of electrical circuits, the error theory.
Results and conclusions. The channel phase separation method in capacitive sensor measuring circuits and its implementation in oblique and in rectangular coordinate systems are considered. The article proposes classification criteria, which have allowed to conduct a systematization of ways of channels phase separation. This systematization will allow to synthesize new ways of providing exclusion of errors caused by non-ideal components and parasitic cable capacitance.
