Abstract :
In this paper, hybrids based on current-sensing and repeaters are proposed for on-chip interconnects in an effort to overcome the limitations of these techniques. A novel receiver for current-sensing results in static power savings and allows an easier transition from current-sensing to traditional full rail voltage signals. Measurements of hybrids on a 0.18-m CMOS technology show significant gains over repeater insertion in delay across wire lengths. Hybrids can also be used in placement constrained and low-noise scenarios to achieve delay and power benefits.
