专利汇可以提供Switching circuit making use of josephson effect专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain switching by the quantum interference effect between Josephson elements, by excluding a magnetically coupled circuit by employing a direct applying method for control current.
CONSTITUTION: As gate current IG is supplied to gate input terminal PG, Josephson effect elements JJ
1 and JJ
2 , and JJ
3 and JJ
4 are biased in the zero-voltage state via two paths extending to the earth-side terminals in the closed loop. Once control current IC using the node between JJ
1 and JJ
2 as input terminal PC is applied, all or some of Josephson effect elements charge in voltage from the zero-voltage state by the mutual quantium interference effect as JJ
2 in the shortest path extending to earth-side terminal PE is placed in the voltage state and gate current IG is switched as current IG' flowing through line 4 to resistance 5. To set it in the original zero- voltage state as switching, cutting off control current IC or decreasing gate current IG is done.
