  • Apparatus and method for supplying power to portion of integrated circuit via weak-strong and strong-only switch cells
    Patent number: 9705491
    Abstract: A power gating circuit including a set of weak-strong switch cells and strong-only switch cells daisy chained together. Each of the weak-strong cell is layout (footprint) compatible with the strong-only cell such that swapping a weak-strong cell for a strong-only cell or vice-versa during the design phase of the power gating circuit does not affect routing to or the timing operation of the circuit to which the power gating circuit supplies power. This allows the ratio of weak to strong switches for minimizing in-rush currents to be optimally set during the design phase of an IC. Each of the weak-strong cells couples power rails together via a weak transistor in response to a weak enable signal, and via a strong transistor in response to a strong enable signal. Each of the strong-only cell couples the power rails together via weak and strong transistors in response to the strong enable signal.
