A Josephson vortex-flow device
Abstract
An inverting, nonlatching switching device capable of analog as well as digital signal amplification is investigated experimentally and theoretically (numerical simulations). The device reported is based on the dynamic properties of long Josephson junctions. It is shown that current gain of the order of 5 can be achieved in a 2.5-μm technology, for small resistive loads of the order of 0.5 Ω.
