由单通量量子(SFQ)电路组成的数模转换器(DAC)可以产生由约瑟夫森关系定义的精确模拟电压。我们一直在开发脉冲频率调制(PFM)型的sfq - dac。对于sfq - dac的电压标准应用,我们将电压幅值和分辨率的目标值分别设置为20 mvpp和10比特。到目前为止,我们已经报道了一个5位,10 μ vpp准正弦电压波形发生器,包括一个pfm型SFQ-DAC和一个片上数字代码发生器。它的峰对峰电压幅值小是由于缺乏片上电压倍增器(VM)。在本文中,我们提出了一个6位,0.25 mvppp准正弦电压波形发生器集成了一个10倍的VM。通过在SFQ-DAC中引入高效的逻辑序列,提高了分辨率。
A digital-to-analogue converter (DAC) consisting of single-flux-quantum (SFQ) circuitry is known to generate accurate analogue voltages defined by the Josephson relationship. We have been developing SFQ-DACs of the pulse-frequency modulation (PFM) type. Toward voltage standard applications of SFQ-DACs, we have set the target values for the voltage amplitude and resolution at 20 mVppand 10 bits, respectively. So far, we have reported a 5-bit, 10-μVppquasi-sine voltage waveform generator comprising a PFM-type SFQ-DAC integrated with an on-chip digital code generator. Its small peak-to-peak voltage amplitude was due to the lack of an on-chip voltage multiplier (VM). In this paper, we present a 6-bit, 0.25-mVppquasi-sine voltage waveform generator integrated with a 10-fold VM. The resolution is improved by introducing efficient logic sequences into the SFQ-DAC.
