我们已经开发和演示了高带宽约瑟夫森电路，以将RSFQ电路的输出连接到室温电子设备。异步直流供电的电压驱动电路被设计成在宽带宽内将RSFQ信号电平放大到2-4 mV范围内的电压输出。这些驱动器电路的特性和测试数据速率高达8 Gb/S。对于(2/SUP 31/-1)位长的伪随机比特序列(PRB)，其中一个驱动器的误码率已测量到7 Gb/S。为了使约瑟夫森电路的数据速率与较慢的室温电子器件相匹配，我们开发了时钟控制移位寄存器，允许以不同的频率移入和移出数据。这些与驱动器集成的电路的完整功能已在低速下演示。集成了电压驱动电路的移位寄存器已经在数据速率高达6 Gb/S的情况下进行了高速测试。
We have developed and demonstrated high bandwidth Josephson circuits to interface the output of RSFQ circuits to room temperature electronics. Asynchronous dc powered voltage driver circuits have been designed to amplify RSFQ signal levels to voltage outputs in the 2-4 mV range, in a wide bandwidth. These driver circuits have been characterized and tested for data rates up to 8 Gb/s. The bit error rate for one of these drivers has been measured up to 7 Gb/s for a (2/sup 31/-1) bit long pseudo-random bit sequence (PRBS). In order to match the data rate of Josephson circuits to slower room temperature electronics, we have developed clock-controlled shift registers which allow shift-in and shift-out of data at different frequencies. Complete functionality of these circuits integrated with the drivers has been demonstrated at low speed. Shift registers integrated with the voltage driver circuits have been tested at high-speed for data rates up to 6 Gb/s.
