| Abstract(in English) | We have designed a multi-input merger using a magnetically coupled SQUID stack in order to merge many signals efficiently. We have confirmed correct operation of the multi-input merger using SQUIDs with up to 16-input by the simulation. We measured the 4-input merger using SQUIDs and verified its correct operation with the dc bias margin of 93%-136%. We also confirmed its high speed correct operation at up to 23 GHz. When we use 16-input mergers using SQUIDs as a merging circuit for an SFQ shift register memory system, for example, we can reduce the delay time and the number of Josephson junctions of the merging circuit for the 4k x 32 bit shift register memory by about 40% and 36% respectively compared to the merging circuit using a 2-input conventional confluence buffer tree. |
