Abstract :
In Si ULSI, the transmission line can be realized by using the inductance of interconnects. In this paper, we design and report driver and receiver circuits for the differential transmission line, which achieve high speed and low power consumption for global interconnect. The delay time and power consumption are evaluated at 2GHz signal frequency. RLC differential transmission line is faster than RC line when interconnect length is over 4mm. RLC line has lower power consumption than RC line over 16mm.
