Design and operation of a series array of voltage doubler cells for rapid-single-flux-quantum digital-to-analog converters

Yoshinao Mizugaki, Yoko Namatame, Masaaki Maezawa

The output voltage of a rapid-single-flux-quantum digital-to-analog converter (RSFQ-DAC) is generated with a voltage multiplier (VM) that comprises multiple voltage mirror cells. We have demonstrated a new operation mode of a voltage mirror cell. It is a second-mode operation that doubles the input voltage, like the second-order Shapiro step. That is, a single cell works as a voltage doubler (VD). In this work, we propose a new parameter set of the VD (VD revision 1: VDr1) that improves the tolerance for multi-stage operation. Experimental results of a 16-stage VDr1 circuit are presented.

Operation of a 4-bit RSFQ digital-to-analog converter based on a binary split-confluence configuration

Naonori Sega, Yuta Somei, Hiroshi Shimada +1 more

Abstract One of the unique applications of single-flux-quantum (SFQ) circuitry is a digital-to-analog converter (DAC) of which the output voltage is defined by the Josephson effect. Recently, we have designed and operated rapid single-flux-quantum (RSFQ) DACs with frequency modulation of SFQ pulse sequences. In this paper, we report our design and test results of a 4-bit RSFQ-DAC based on the configuration of the “sum of selected bits sequence (Σ-SBS)”. By adjusting the timing margins, in addition to the fabrication using the Nb integration process with the critical current density as high as 10 kA/cm2, the maximum output voltage up to 260 μV was demonstrated.

Voltage Doubler Cell for Rapid Single Flux Quantum Digital-to-Analog Converter

Digital-to-analog converters based on rapid single flux quantum circuits (RSFQ-D/A converters) are candidates for the next generation of ac voltage standard. We re-optimized the device parameters of a voltage multiplier (VM) cell, one of the important components in the RSFQ-D/A converter, to implement a new voltage doubler (VD) cell. The output voltage of the VD cell was twice as high as that of the conventional VM cell. We fabricated VD cells using a Nb technology. We confirmed correct operation of the VD cells at input frequencies up to 30 GHz.
