<p>A superconducting circuit system comprises a biasing circuit (100, 101) for producing a bias current that changes periodically, and a superconducting rectifier circuit (30, 50) driven by the bias current. The superconducting rectifier circuit is supplied with a first pulse train including therein positive and negative pulses in synchronization with the bias current and produces a second pulse train of unipolar pulses in response to a transition of a Josephson junction caused by the pulses of the first pulse train. <IMAGE></p> |
