Abstract :
An output voltage of 150 mV was obtained with a risetime of less than 200 ps at the driver, which contained 104 junctions and 2 resistors. The driver was also used to drive a D-HEMT (high-electron mobility transistor), and an output voltage of 0.9 V with a risetime of 500 ps was obtained from the HEMT. This experiment suggests that the Josephson driver developed can be used for a Josephson computer or a SQUID (superconducting quantum interference device) system as an interface gate to drive room-temperature electronic devices.<>
