我们提出了一个完全集成的全数字一位RSFQ自相关器的短毫米波和亚毫米波光谱应用的低速和高速测试的结果。这款16通道器件配有16/spl times/9二进制计数器阵列、片内双过采样量化器和片内时钟，时钟速度高达11 GHz。设计中约瑟夫森结的总数为1672个，而估计的总功耗小于0.1 mW。为了对器件进行高速测试，我们开发了一种专用的16通道室温接口，能够以每通道16 Mbps的输出速率进行实时数据采集。广泛的高速片上测试的自相关器也已执行，在模拟和数字模式，在后一种模式与一个额外的片上时钟控制器。所有芯片均采用HYPRES的标准3.5 /spl mu/m-10 /spl mu/A//spl mu/m/sup 2/Nb-三层工艺制造。我们还提出了一个新的概念，128通道自相关器系统建立在8个独立的相同的芯片上，每个芯片约2,500个约瑟夫森结，即在当今的制造技术范围内。
We present the results of low- and high-speed testing of a fully integrated all-digital one-bit RSFQ autocorrelator for short-millimeter and submillimeter wave spectrometry applications. The 16-channel device, complete with a 16/spl times/9 array of binary counters, on-chip double-oversampling quantizer and on-chip clock was operational at clock speeds of up to 11 GHz. The total number of Josephson junctions in the design was 1672, while the estimated total power dissipation was less than 0.1 mW. For high-speed testing of the device we have developed a specialized 16-channel room-temperature interface capable of real-time data acquisition at a 16 Mbps-per-channel output rate. Extensive high-speed on-chip testing of the autocorrelator has also been performed, both in analog and digital modes, in the latter mode with an additional on-chip clock controller. All chips were fabricated in HYPRES' standard 3.5 /spl mu/m-10 /spl mu/A//spl mu/m/sup 2/ Nb-trilayer process. We also present a new concept of a 128-channel autocorrelator system built on 8 independent identical chips with approximately 2,500 Josephson junctions per chip, i.e. within the reach of the present-day fabrication technology.
