“…In ADCs using switched capacitors, the parameters are determined by the ratio of the capacitors, not their nominal values. In addition, the modern development of integrated circuit manufacturing in CMOS (complementary metal-oxide semiconductor) technology has enabled the realisation of capacitors with many times higher accuracy compared to resistors (from two to seven times), improving their temperature characteristics and reducing power consumption [4][5][6]. This greatly simplifies the interworking of the ADC's component blocks (unit components) and allows building a high-speed ADC with high precision.…”

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.
