Integrated circuit device and method of implementing power gating within an integrated circuit device

摘要

An integrated circuit device comprises at least one power gating arrangement, including at least one gated power domain, and at least one power gating component operably coupled between at least one node of the at least one gated power domain and at least a first power supply node. The at least one power gating component is arranged to selectively couple the at least one node of the at least one gated power domain to the at least first power supply node.

1. An integrated circuit device comprising:
a power domain; a power gating component operatively coupled between a node of the power domain and a power supply node to electrically couple the node of power domain to the power supply node when enabled; an isolation component operatively coupled between a chargeable device and the node of the power domain to electrically couple the chargeable device to node of the power domain when enabled; and a power gating control module coupled to the isolation component and to the power gating component to electrically de-couple the chargeable device from the node of the power domain, to electrically couple the power supply node while the chargeable device is electrically de-coupled from the node of the power domain, and, after waiting for a non-zero period of time and while the node of the power domain is electrically coupled to the power supply node, electrically couple the chargeable device to the node of the power domain.
