Differential transmission line interconnect for high speed and low power global wiring

Abstract

This paper proposes transmission line interconnect, which achieves high speed and low power consumption for global interconnects. The delay time and power consumption are evaluated at 4 Gbps signal frequency. RLC differential transmission line is faster than RC line when interconnect length is over 2.4 mm. RLC line has lower power consumption than RC line over 7.0 mm. Increasing interconnect area can be suppressed by using the diagonal-pair line structure as the differential transmission line.
