ANALOG-TO-DIGITAL CONVERTER USING SUPERCONDUCTING MATERIAL

摘要

An analog-to-digital converter using superconducting material. The converter includes a converter portion having a plurality of series-connected superconducting current channels for which different values of a certain critical condition are set, the values differing from one another by a fixed amount. The converter also includes a detector portion including means for detecting the interruption of the flow of a superconducting current in each of said superconducting current channels, the analog-to-digital converter outputting a digital signal indicative of the associated change in a physical quantity related to said critical condition and which is applied as an input to the converter portion.
