本文介绍了一种9位可编程单通量量子（SFQ）数模转换器（DAC）的设计和工作原理。DAC包括一个9位可变SFQ脉冲数乘法器和一个100倍电压乘法器。采用SFQ脉冲频率调制技术对模拟输出电压进行编码。DAC采用铌约瑟夫森集成技术制造。它的输出电压波形，其幅度高达2.54 mV pp，是由来自室温数据发生器的数字输入信号控制。
The design and operation of a 9 bit superconductive single-flux-quantum (SFQ) digital-to-analogue converter (DAC) are presented. The DAC comprises a 9 bit variable SFQ pulse number multiplier and a 100-fold voltage multiplier. An SFQ pulse-frequency modulation technique is employed for coding the analogue output voltage. The DAC is fabricated using an Nb Josephson integration technology. Its output voltage waveform, the amplitude of which is up to 2.54 mV pp, is controlled by digital input signals from a room-temperature data generator.
