Abstract

Global on-chip data communication is becoming a concern as the gap between transistor speed and interconnect bandwidth increases with CMOS process scaling. In this paper we show how a special form of equalization, pulse-width pre-emphasis, can significantly increase the data rate for a given length of uninterrupted interconnect, especially if used in combination with lowohmic termination and twisted differential interconnects. To validate these techniques, a bus-transceiver test chip in a 0.13μm, 1.2V, 6M copper CMOS process has been designed. The chip uses 10mm long differential interconnects with wire widths and spacing of only 0.4μm. With transceivers operating in conventional mode, the chip achieves only 0.55Gb/s/ch. The achievable data rate increases to 3Gb/s/ch (consuming 2pJ/bit) if pulse-width pre-emphasis and low-ohmic termination are turned on.
