In this paper, a novel mixed design of low-swing selftimed regenerator (LS-STR) is presented. Th e new design reduces the energy-delay product (EDP) and eliminates a fabrication constraint. Th us, the LS-STR is suitable for long global on-chip interconnects. Th e proposed scheme is simulated using CMOS 90- nm technology at 1.0 V power supply rail, for signal transmission along a 10-mm length line. Th e simulation results for different wire widths reveal that the propagation delay is reduced by 39.1% for iso-power mode when compared with the delay of optimal repeater insertion. Also, up to 23.2% power reduction is achieved in the iso-delay mode. A key advantage of the proposed LS-STR is that it employs neither multiple-threshold process technology nor an extra and different power supply rail, while the noise margin remains in an acceptable level.
