Abstract
A new driver circuit is developed for chip-to-chip logic signal transmission in Josephson computers. Multiple reflection noises between driver and connector impedance discontinuities may cause false logic operations in the driver and receiver circuits. Based on this factor, the driver is designed to match the impedance between the driver and transmission line in order to reduce multiple reflections. Since the noises due to the first reflections remain in this driver system, its use is limited to special cases. When used in these cases, however, the driver provides a shorter transmission path delay than Klein's driver. Experimentation shows that the driver has perfect impedance matching effects within a wide bias current margin (±26 percent).
