| Abstract | (in Japanese) | (See Japanese page) |
| (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. | |
