| Description | We evaluate the input-output characteristics of a 1000-fold voltage multiplier designed for single-flux-quantum (SFQ) digital-to-analog converters. We have designed and fabricated a 999-stage double-flux-quantum amplifier using a Nb/AlOx/Nb integration technology. In experiments, we have used two methods of feeding the input SFQ pulse train. The one is an overbiasing method, i.e., the input SFQ pulse train is generated at an overbiased input junction. A 1000-fold voltage multiplication with errors less than +/-1% has been confirmed for input voltages of up to 27 μV, of which the corresponding Josephson frequency is 13 GHz. In the other method, a dc/SFQ converter is used for feeding the input SFQ pulse train. A 1000-fold voltage multiplication with an error of +/-0.03% has been obtained for an input frequency of 600 MHz, of which the corresponding Josephson voltage is 1.2 uV. In experiments, errors in measured voltages are likely to limit the accuracy in evaluation of the multiplication factor. | |||||||||||||
