ABSTRACT:
A self-resetting Josephson device circuit is disclosed which responds to one transition of a circuit input by producing a short output pulse, and which resets itself in response to another, complementary transition of said circuit input. The Josephson device circuit includes a first and second Josephson device, one coupling a dc source to a current sink, said second connected in series with an inductor between said current source and sink. The circuit input, which is of a square waveform, is applied, in series, to first control circuits of the first and second Josephson devices. The second Josephson device has a second control circuit to which dc is applied of polarity opposite to the current in the first control circuit and of an amplitude substantially the same as the amplitude in the first control circuit when said circuit input is present. An output circuit includes a third Josephson device coupled in series with a second inductor and a resistor, with the series circuit coupled to said dc source. With the output circuit including the third Josephson device connected across the first Josephson device, an output pulse is produced across the second inductance and resistance on a high going transition of the circuit input. On the other hand, if the output circuit is connected across the second Josephson device then an output taken across the second inductor and resistance is produced in response to a low going transition of the circuit input. In either case, the circuit responds to the complementary transition by resetting itself.
