Lossy transmission line effects in a thin-film multichip module

The author reports results of an investigation of the chip-to-chip signal propagation properties in a thin-film multichip module. The lossy transmission effects on the CMOS interface were analyzed by SPICE simulation and compared with an emitter-coupled logic interface. It is proved that CMOS-based multichip modules are less affected by the line resistance and have less power dissipation. An example of a CMOS-based multichip module using chip-on-wafer technology is introduced.<
