Superconducting quantizer and A/D converter system

摘要

A periodic superconducting device signal quantizer for the fine resolution of the magnetic flux quantum PHI 0=2*10-15 Wb realized by a phase wheel 20 or a phase tree 100. The signal quantizer is used in conjunction with a superconducting A/D converter for achieving the 8-11 bit A/D converters with gigahertz, multi-gigahertz bandwidth. A method for an extra-bit resolution of the analog signal using the signal quantizer is described.
