Abstract
A single flux quantum (SFQ) circuit includes a radio frequency (RF) to direct current (DC) conversion stage. A DC to RF current conversion stage is coupled to a single output of the RF to DC conversion stage. The DC to RF current conversion stage includes a plurality of series stacked Josephson Junctions (JJs) having n stages, configured to convert a DC current received from the RF to DC conversion stage and reconvert the DC current to an RF tone.
