Abstract

A circuit is described which functions as a precision electronic analog of a resistively shunted, capacitive Josephson junction. This design offers significant improvements over earlier simulators, particularly because no analog switches are required, and also because high performance op-amps have been matched to the demands of the circuit. The junction analog is used to generate I-V curves, and to model the dynamics when an abrupt bias pulse is applied. The simulator is shown to be very accurate when tested against numerical solutions for the same systems.
