Modelling a New Multifunctional High Accuracy Analogue-to-Digital Converter with an Increased Number of Inputs

Abstract

This paper presents a multi-input analogue-to-digital functional converter manufactured using switched capacitors. A new method of multifunctional analogue-to-digital processing was tested, which allowed the number of inputs to be increased to 10 without compromising accuracy. An algorithm was developed, and the converter’s operation was modelled based on this method. It was found that error values are not significantly affected by the number of input voltages. The value of the lowest input voltage has a decisive influence on the conversion time. The examined multi-input analogue-to-digital functional converter performs multiplication, division, exponentiation, and root extraction operations. The exponent of the power and the degree of the root corresponds to the number of inputs of the converter.
