POWER DISTRIBUTION NETWORK (PDN) CONDITIONER |
| 摘要 |
Systems and methods for conditioning a power rail (e.g., reducing voltage droops and/or voltage overshoots on the power rail) are described herein. In one embodiment, a power circuit comprises a capacitor coupled to a high-voltage rail, and a droop slope limiter (DSL) coupled between the high-voltage rail and a power rail. The DSL is configured to detect a downward voltage slope on the power rail, and to control current flow from the high-voltage rail to the power rail through the DSL based on the detected downward voltage slope. |

1. A power circuit, comprising:
a capacitor coupled to a high-voltage rail; and a droop slope limiter (DSL) coupled between the high-voltage rail and a power rail, wherein the DSL is configured to detect a downward voltage slope on the power rail, and to control current flow from the high-voltage rail to the power rail through the DSL based on the detected downward voltage slope. |
