ABSTRACT:
A superconductor multi-level quantizer is disclosed, which quantizer includes a number N of Josephson junction (JJ) comparators connected in parallel to a common input node. The quantizer further includes at least one flux bias device. Each flux bias device is capable to adjust the flux threshold for at least one of the JJ comparators. The quantizer is so configured a feedback current from the output is capable to shift the flux threshold for each of the JJ comparators.
