Спосіб аналого-цифрового перетворення і пристрій для його реалізації

Abstract

The invention relates to digital measuring technic and computation engineering. A method and a device of digital-analog conversion may be used for conversion of analog quantities to digital quantities. The technical result is enhancement of parametric reliability of the converter that results in widening scope of application of the device that is attained by device operating in two modes: self-calibration and basis conversion. Self-calibration mode is characterized in that codes of operational significances of place values and zero error are registered and used for basis conversion mode. In basis conversion mode a balancing signal and auxiliary analog signal are shaped in every i-th cycle, after that signals are compared with input analog signal, depending on results of comparison in all cycles, output code is formed.
