Title: Method for constituting superconduction circuit
Inventor: SUGANO TAKUO
IPC: H03K19/195
Filed: 1984-03-24
Abstract: PURPOSE:To widen sufficiently the operating region by connecting two unijunction superconduction quantum interferometers with a superconduction wire and applying assymetrically a bias current to eliminate the need for a three-phase close to transmit unidirectionally the signal. CONSTITUTION:When an input current is applied, a current flowing to the left Josephson junction 1 exceeds the critical current value of the junction, the Josephson junction is switched to the voltage state momentarily, a counter clockwise circulating current flows to the left loop and a clockwise circulating current is generated in the middle loop to satisfy the fluxoid quantum condition. The current flowing to the right Josephson junction 2 exceeds the critical current of the junction by flowing the circulating current, the Josephson junction is switched momentarily to the voltage state and the clockwise circulating current is propagated to the right loop. As a result, the magnetic flux quantum toward this side exists in the left loop and the magnetic flux quantum toward the other side exists in the right loop and this state is allowed to correspond to the logical state ''1''.
