| Description | We present design of IQVNS based on rapid single flux quantum (RSFQ) circuit technology. An IQVNS chip consists of three main subsystems, a pseudorandom number generator (PRNG), a variable pulse number multiplier (VPNM) and a voltage multiplier (VM), which is a simplified version of a RSFQ digital-to-analog converter. PRNG generates a sequence of pseudorandom numbers according to the maximum-length sequence, which is implemented with a shift register and an exclusive OR gate. The SFQ pulses generated with PRNG are multiplied and converted into a bipolar waveform with VPNM and VM. A calculable reference noise voltage is eventually obtained based on the Josephson effect. Power spectrum densities have been calculated for the designed IQVNS. With parameters for measurements of the triple point of water, 273.16 K, we obtained pseudo-white spectra up to 0.65 MHz, a cut-off frequency of our JNT system. We also discuss the effects of jitter on the accuracy of the output reference noise voltage. | |||||||||||
