Abstract :
A new GaAs current-mode (CM) chip-to-chip interconnection circuit is presented that provides high signal transfer speed with a 50 Ω active termination and reduced input voltage swing. The power dissipation is shown to be 1/8 of an ECL I/O at the same data rate, 4 mW per pin, using a standard 2 V power supply. The driver-receiver operates with a current swing under 1 mA and provides a large noise margin
