New Method for Logarithmic Analogue-to-Digital Conversion Using Switched Capacitors with a Variable Logarithmic Base

Abstract

This article is devoted to the development of a new method of logarithmic analogue-to-digital conversion using switched capacitors with a variable logarithmic base. The essence of the method and its implementation are presented. Mathematical models have been developed, analysis has been carried out and errors have been assessed. It has been demonstrated that the developed converters, using the proposed method, significantly outperform known analogous converters: for input voltages ranging from 1 mV to 10 V, the processing error does not exceed 0.001% with a processing time not greater than 105 µs (microseconds).

Synthesis of an electronic control module for a selected technological node with a focus on its automation

“…N the design of automation systems, the analysis and synthesis of the conceptual diagram of the device [1,2,3] are of particular importance. Proper implementation of the diagram shortens the time of execution, preparation, and verification of the technical documentation of the device [4,5,6].…”
