PURPOSE:To obtain a DC driven circuit with large signal amplitude voltages by a method wherein two Josephson device free of hysteresis in their voltage/current characteristics are serially combined and a first controlling line is provided in their vicinity and a second in the vicinity of one of the two devices. CONSTITUTION:A first Josephson device 401 lacking a hysteresis featue in its voltage/current characteristics has a terminal connected to a power source terminal 311. The other terminal is connected to a circuit output terminal 310 and to one of the terminals of a second Josephson device 402 also lacking a hysteris feature. The other terminal of the device 402 is grounded. Next, a first load resistor 303 is provided across the terminals 311 and 310, and a second load resistor 304 is provided across the terminal 310 and the ground. A second controlling circuit 308 with a constant current source 309 is provided in the vicinity of the network just referred to. And a first controlling circuit 307 with terminals 305 and 307 is positioned in the vicinity of the two devices. The magnetic fluxes generated by the two devices are rendered to interlock, or to neutralize, each other. |
