Abstract
A Josephson current regulator circuit is described for regulating the gate current to a Josephson load device. The regulator circuit is located between the source of the gate current and the Josephson load, and is comprised of Josephson devices having a critical current less than the critical current of the Josephson load device. Each of the Josephson regulator devices has at least two states dependent upon the magnitude of the gate current. A resistance is associated with each of the Josephson regulator devices so that, when the state of the Josephson regulator device is changed, resistance is either introduced or removed from the circuit connecting the source and the Josephson load. This adjusts the magnitude of the gate current and maintains within a specified range the ratio of the gate current to the critical current of the Josephson load device.
