快速单通量量子数模转换器（RSFQ-DAC）目前正在开发中，用于交流电压标准应用。电压倍增器（VM）用于精确放大输入电压，是RSFQ-DAC的关键器件。由于传统VM的偏置电流量与其倍增因子成比例地增加，因此我们一直在寻找一种基于不同原理操作的VM器件。在本文中，我们报告了我们的设计，1000倍VM包括双通量量子放大器（DFQA）的偏置电流的量是独立于其倍增因子。使用2.5 kA/cm 2Nb工艺制造测试电路。我们确认，实验结果表明，1000倍的操作高达13.2 GHz的输入SFQ脉冲重复频率。
Rapid-single-flux-quantum digital-to-analogue converters (RSFQ-DACs) are now under development for ac voltage standard applications. The voltage multiplier (VM), which precisely amplifies the input voltage, is a key component for RSFQ-DACs. Because the amount of bias current for a conventional VM increases in proportion to its multiplication factor, we have been looking for a VM device which is operated on a different principle. In this paper, we report our design of a 1000-fold VM comprising double flux quantum amplifiers (DFQAs) of which the amount of bias current is independent of its multiplication factor. Test circuits were fabricated using a 2.5 kA/cm2Nb process. We confirm that the experimental results demonstrate the 1000-fold operation up to 13.2 GHz input SFQ pulse repetition frequency.
