DYNAMIC-TYPE PARALLEL ANALOG-DIGITAL CONVERTER

摘要

Dynamic-type parallel analog-digital converters relate to the field of electronic radio technology associated with the digital processing of analog signals. Two variants of dynamic formation of an output code are employed in converters, making it possible to limit the number of comparators by the number of bits of an output binary code. In the first variant in the converters an input voltage is compared in comparators, connected in parallel, to a dynamic system of reference voltages that track the state of the digital outputs of the device. In the second conversion variant a constant reference voltage applied to similar inputs of a group of comparators is compared to the voltages being converted, which are obtained by linear conversions of the input voltage by the output binary code.
