Abstract
One example includes a current driver system. The system includes a current source configured to provide a source current to a transition node. The system also includes a Josephson latch comprising at least one Josephson junction stage. The at least one Josephson junction stage can be configured to conduct the source current from the transition node as a current-clamped bias current in a deactivated state of the Josephson latch. The Josephson latch can be configured to activate in response to the bias current and a trigger pulse to switch the at least one Josephson junction stage to a voltage state to conduct at least a portion of the source current from the transition node as an output current to a load in response to activation of the Josephson latch.
