✦ Synopsis

Studies on the propagation of picosecond pulses in coupled microstrip line interconnections on silicon integrated circuit substrates are presented. The effects of conductor and dielectric losses in the transmission line on the distortion, delay and attenuation of picosecond pulses are studied in detail. A direct comparison is made with the propagation characteristics of interconnects using ordinary metals and high-temperature superconductors such as YBa2Cu3O7. The results generally show the advantages of using high-temperature superconductor tracks on low-loss integrated circuit substrates such as GaAs. Hoaever, even in this case, geometrical dispersion can cause distortion on the pulses and it is therefore an important factor to be considered.
