Abstract—Increased need for power density and close • Shorter signal transmission time because of reduced
integration of power subsystems associated with interconnect resistance;
superconductive motors/generators, degaussing coils, energy • Increased integration density because of the higher
storage modules and cables leads one to consider the merits of semiconductor substrate and metal thermal conductivities;
refrigerating the power electronics down to cryogenic • Improved digital and analog circuit performance such as
temperatures. High-temperature ponents
noise margins, gain-bandwidth products or slew rates.
