Power Gating(PG) is very effective to reduce the leakage power. Recently proposed Zigzag power gating(ZPG) technique has the visible advantage on short wake-up time. However, additional PG transistors consume intolerable area overhead. Basing on the BPTM-65nm model, we propose a new optimization methodology of the selective ZPG technique for the wide-used dual-threshold voltage CMOS circuit design...
Designing a power-gating structure with high performance in the active mode and low leakage and short wakeup time during standby mode is an important and challenging task. This paper presents a tri-modal switch cell that enables implementation of multimodal power gating, including active, data-retentive drowsy, and deep sleep modes. A circuit realization and design methodology are presented that allow...
Process variation is recognized as a major source of parametric yield loss, which occurs because a fraction of manufactured chips do not satisfy timing or power constraints. On the other hand, both chip performance and chip leakage power depend on supply voltage. This dependence can be used for converting the fraction of too slow or too leaky chips into good ones by adjusting their supply voltage...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
