Low power current mode multi-valued logic interconnect for high speed interchip communications

A new GaAs current mode (CM) chip-to-chip interconnection circuit is presented that provides high signal transfer speed with a 50 /spl Omega/ active termination and reduced input voltage swing. The power dissipation is shown to be 1/8 of an ECL I/O. The ternary logic version of it can reduce wiring by half and eliminate clock skew problems while still keeping the low power dissipation.
