New principle of integrating analog-digital conversion with tactless bit-by-bit balancing

Abstract

In article the new principle of constructing the closed integrating analog-digital converter (ADC) of tactless bit-by-bit balance with integrated in a closed circuit ADC by the digital-analog converter (DAC) is considered. The structure and timing diagrams are provided. The analysis of static and dynamic characteristics is given as well as the results of experimental investigations. It is mentioned that the application of the integrator makes it possible to provide high noise stability, reliability of the device, also tactless bit-by-bit control allows to provide higher operating speed in comparison with integrating ADC.

Keywords: analog-digital converter, integrating converter, integrator, relay element, multizone scanning converter, digital-analog converter, tactless bit-by-bit balancing.
