| A superconducting switching amplifier embodying the invention includes superconductive devices responsive to input/control signals for clamping the output of the amplifier to a first voltage or to a second voltage. The amplifier includes a first set of superconducting devices serially connected between a first voltage line and an output terminal and a second set of superconducting devices serially connected between the output terminal and a second voltage line. The first set and the second set of devices are operated in a complementary fashion in response to control signals. When one of the first and second sets is driven to a superconducting (zero resistance) state the other set is driven to a resistive state. In accordance with the invention, the devices of each set are laid out in a pattern and driven in a manner to enable all the devices of each set to be driven to a selected state at substantially the same time. In one embodiment, the devices in each set are superconducting quantum interference devices (SQUIDs). Four sets of superconductive devices may be interconnected to function as a differential switching amplifier. The operating voltage applied to an amplifier may be varied to provide additional shaping of the output signal. | ||||||

| A single flux quantum (SFQ) pulse is generated (502) by injecting a superconductor output signal as a first signal at a “start” input (108) coupled to a superconductor delay element (104). The SFQ pulse is reflected (504) back and forth between first and second superconductor reflectors (102, 106) coupled to opposite ends of the superconductor delay element, thereby generating a time-disperse plurality of SFQ pulses at an output (110) coupled to the superconductor delay element. Thereafter, a second signal is input at a “stop” input (112) coupled to one of the first and second superconductor reflectors, thereby interrupting (506) the reflecting of the SFQ pulse at the one of the first and second superconductor reflectors, thus ending the generating of the time-disperse plurality of SFQ pulses at the output. | ||||||

| A superconductor signal amplifier which receives an extremely small high-frequency signal having a frequency of tens of GHz generated in a superconductive circuit, amplifies the voltage of the high-frequency signal without a decrease in frequency, and outputs the thus amplified high-frequency signal from the superconductive circuit. At an output part of a single flux quantum circuit using a flux quantum as a binary information carrier, there are provided a superconductive junction line for flux quantum transmission and a splitter for simultaneously producing two flux quanta from a flux quantum. According to the number of plural series-connected SQUIDs, a plurality of flux quantum signals are generated and input to the plural series-connected SQUIDs so that the SQUIDs are simultaneously switched to a voltage state. In each SQUID pair comprising two SQUIDs, a part of an inductor is shared by the two SQUIDs for reduction in inductance, thereby increasing an output voltage of the series-connected SQUIDs. Furthermore, a magnetic shielding film formed under each SQUID is electrically isolated from ground to prevent a signal delay due to a parasitic capacitance. | ||||||
