Digital to analog conversion based on processing of the SFQ pulses

Two novel circuits of DC voltage multipliers have been designed, fabricated using a 3.5 mu m 1000 A/cm/sup 2/ niobium trilayer technology, and successfully tested at low frequencies. A novel primary digital-to-analog (D/A) converter based on the processing of single-flux-quantum (SFQ) pulses has been suggested. The performance of analog-to-digital (A/D) converters combined from such primary D/A converters and voltage multipliers is discussed.<>
