This paper describes a differential current-mode bus architecture based on driver pre-emphasis for on-chip global interconnects that achieves high-data rates while reducing bus power dissipation and improving signal delay latency. The 16-b bus core fabricated in 0.25-µm complementary metal-oxide-semiconductor (CMOS) technology attains an aggregate signaling data rate of 32 Gb/s over 5-10-mm-long lossy interconnects. With a supply of 2.5 V, 25.5-48.7-mW power dissipation was measured for signal activity above 0.1, equivalent to 0.80-1.52 pJ/b. This work demonstrates a 15.0%-67.5% power reduction over a conventional single-ended voltage-mode static bus while reducing delay latency by 28.3% and peak current by 70%. The proposed bus architecture is robust against crosstalk noise and occupies comparable routing area to a reference static bus design. |
