Development of the integrating analog-to-digital converter for distributive data acquisition systems with improved noise immunity

Abstract

Requirements for the noise immunity of the universal ADC for sensor signal conversion are formulated. The structure of the antijamming dual slope ADC for use in distributive adaptive and intelligent measurement and control systems is described. The normal mode rejection calculated by simulation of ADC operating modes and by experimental research is compared. It has been shown that the sets of operating modes of the developed ADC compared with adaptive properties provide high flexibility of this ADC for determining metrology characteristics of the developed ADC setting.
