Abstract :
A polarity-convertible Josephson driver, which consists of four two-junction interferometer gates and three resistors, has been developed and successfully tested. Driver test chips have been fabricated by using a niobium planarisation technique. Polarity-convertible operations have been experimentally tested and an approximately ±43% gate current margin has been obtained
