Abstract :
Capacitively-driven on-chip wires reduce both latency and energy compared to repeaters. A series coupling capacitance offers preemphasis to lower wire delay, reduces the driven load, and lowers the wire voltage swing without a second power supply. A 0.18mum CMOS testchip shows 10.5times energy savings at a 50mV swing compared to full-swing repeated wires, and a 3times gain in wire bandwidth
