ABSTRACT:
A SQUID comparator having two junctions configured so that its operating characteristics are substantially the same as a single junction SQUID. In particular, the ratio of the critical current of these two junctions is selected to avoid introduction of hysteresis. An n-bit single pass comparator is present that can produce 4-bit A/D conversion up to 10 GHz. A method is implemented to remove effects of dynamic hysteresis by use complementary comparators.
