Abstract :
The letter describes a Josephson-junction analogue/digital (A/D) convertor using redundant coding and balanced SQUID comparators. It is shown that application of this scheme leads to a major increase of the critical current margins (up to ~20%), eliminating the need for adjustment of each comparator.
