ABSTRACT:
In a superconducting digital to analog converter, shunt branches of a ladder resistor network are connected to corresponding Josephson devices, the states of which are switched by a digital signal. Currents following through the Josephson devices or load resistors of the Josephson devices are collected to obtain an analog signal corresponding to the digital signal.
