介绍并分析了功率门控结构中功率模式跃迁引起的地反弹现象。为了减少地跳，我们提出了一种新颖的功率门控结构，其中休眠晶体管以非均匀的步进方式导通。我们的电源门控结构减少了配电网络中的峰值电流和电压毛刺的幅度，以及稳定电源和接地所需的最短时间。用PowerSpice固定在封装模型中的实验仿真结果证明了所提出的功率门开关噪声抑制技术的有效性。
We introduce and analyze the ground bounce due to power mode transition in power gating structures. To reduce the ground bounce, we propose novel power gating structures in which sleep transistors are turned on in a non-uniform stepwise manner. Our power gating structures reduce the magnitude of peak current and voltage glitches in the power distribution network as well as the minimum time required to stabilize power and ground. Experimental simulation results with PowerSpice fixtured in a package model demonstrate the effectiveness of the proposed power gate switching noise reduction techniques.
