Functional Converter for Intelligent Sensor and Its Layout Design

Abstract

Recently, the number of cyber-physical systems and systems with embedded sensors has been increasing. In order to minimize the amount of information transmitted, a new paradigm is being developed that involves moving data processing as close as possible to the point of its generation. At the same time, there is a need to create devices that will provide computations near the sensors. The article considers an approach to the primary processing of a quasi-digital sensor signal. The authors show a variant of the organization of calculations in pulse form, based on the method of small increments. The method is focused on the usage of simple logical elements with the realization of a transfer function in the base of increment/decrement operations. The solution proposed by the authors is effective in terms of simplicity of hardware implementation and can be used to connect sensors with pulse output to digital processing systems. The considered circuit solutions can be used for the implementation in programmable logic device of different levels of complexity, as well as for the manufacture of the transducer in the form of a custom circuit.
