ABSTRACT:
A parallel analog to digital converter which uses a dual-rank arrangement of flash converters. The flash converters have Josephson junctions and act as a sample and hold circuit. The dual-rank arrangement allows a smaller number of comparators to be used than in a pure parallel conversion scheme, which also makes encoding the outputs of the flash converters less complex. The analog to digital converter includes an encoder which controls its output interferometers based on the net flux generated by combinations of input currents into the encoder.
