| Abstract(in English) | Rapid-single-flux-quantum digital-to-analogue converters (RSFQ-DACs) are now under development for ac voltage standards Recently, we have been developing RSFQ-DACs based on frequency modulation of the SFQ pulse train, in which a voltage multiplier (VM) is required to multiply the voltage by a fixed factor 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 based on a different operation principle In this paper, we report our design of a 1000-fold VM comprising double flux quantum amplifiers (DFQAs) of which the total bias current is independent of its multiplication factor Test circuits were fabricated using a 2 5 kA/cm2 Nb process We confirm that the experimental results demonstrate the 1000-fold operation up to 13 2 GHz input SFQ pulse repetition frequency |
