Recent development of SFQ circuits technology enabled us to make large SFQ circuits including more than ten thousand Josephson junctions. However, the total bias current for such large circuits is now over one ampere. An increase of bias current causes several problems for circuits operation, such as large magnetic fields and ground return currents. To solve this problem, we investigated current recycling, which can drastically reduce the total bias current of SFQ circuits. For realizing the current recycling, signal transmission between SFQ logic circuits located on different grounds is required. We designed two types of inductively coupled SFQ pulse transfer circuits and confirmed their correct operations. We also studied circuit structures of effective coupling for the SFQ pulse transfer circuits. |
