Abstract
The present invention is directed to dynamically adjusting the threshold of a magnetic flux sensitive comparator to permit matching of circuit elements for use in A/D converters. For example, comparator threshold variations can be adjusted or programmed to compensate for variations in device components such as resistors. By overcoming parameter matching problems, superconductive A/D converters designed in accordance with the present invention can provide relatively high bandwidth and sampling rates.
