摘要： One example describes a superconducting current source system comprising a linear flux-shuttle. The linear flux-shuttle includes an input and a plurality of Josephson transmission line (JTL) stages. Each of the JTL stages includes at least one Josephson junction, an output inductor, and a clock input. The linear flux-shuttle can be configured to generate a direct current (DC) output current via the output inductor associated with each of the JTL stages in response to the at least one Josephson junction triggering in a sequence in each of the JTL stages along the linear flux-shuttle in response to receiving an input pulse at the input and in response to a clock signal provided to the clock input in each of the JTL stages.

摘要： An isochronous receiver system is provided and includes a single flux quantum (SFQ) receiver to receive a data signal from a transmission line. The single flux quantum receiver then converts the data signal to an SFQ signal. The system also includes a converter system to convert the SFQ signal to a reciprocal quantum logic (RQL) signal and to phase-align the RQL signal with a sampling phase of an AC clock signal.

摘要： One example includes an isochronous receiver system. The system includes a pulse receiver configured to receive an input data signal from a transmission line and to convert the input data signal to a pulse signal. The system also includes a converter system comprising a phase converter system. The phase converter system includes a plurality of pulse converters associated with a respective plurality of sampling windows across a period of an AC clock signal. At least two of the sampling windows overlap at any given phase of the AC clock signal, such that the converter system is configured to generate an output pulse signal that is phase-aligned with at least one of a plurality of sampling phases of the AC clock signal based on associating the pulse signal with at least two of the sampling windows.

摘要： Embodiments of the present invention provide an approach for utilizing a sense amplifier to select a suitable circuit, wherein a suitable circuit generates a voltage that is greater than or equal to a configurable reference voltage. An amplifier gain selector selects a voltage gain of a sense amplifier having input terminals, auxiliary inputs, an output, an array of resistive loads, and the amplifier gain selector. Auxiliary inputs are utilized to nullify direct current (DC) offset voltage of the sense amplifier. Combinatorial logic circuitry connects the input terminals of the sense amplifier to output terminals of a circuit that is within a group of circuits. A comparator circuit determines if the circuit generates a voltage greater than or equal to a configurable reference voltage, based on the output of the sense amplifier.
