摘要：
We have used a 2.5 kA/cm(2) standard Nh junction technique to fabricate superconducting driver circuits and here present experimental results. The driver consists of 16 resistively shunted stacked junctions and an input junction. It is capable of converting a single Bur quantum pulse to 10 mV at 3 GHz, and 7 mV at 10GHz. The driver is thus a potential high-speed output interface between superconducting single-flux-guantum (SFQ) systems and room-temperature semiconductor systems.
