INTEGRATED CIRCUIT DEVICE AND METHOD OF IMPLEMENTING POWER GATING WITHIN AN INTEGRATED CIRCUIT DEVICE

摘要

An integrated circuit device (200) comprises at least one power gating arrangement (205). The at least one power gating arrangement (205) comprises at least one gated power domain (210), and at least one power gating component (220) operably coupled between at least one node (215) of the at least one gated power domain (210) and at least a first power supply node (202). The at least one power gating component (220) is arranged to selectively couple the at least one node (215) of the at least one gated power domain (210) to the at least first power supply node (202). The at least one power gating arrangement (205) further comprises at least one isolation component (240) operably coupled, for example in series, between at least one chargeable device, for example a capacitance (230) and the at least one node (215) of the at least one gated power domain (210), the at least one isolation component (240) being arranged to selectively couple the at least one capacitance (230) to the at least one node (215) of the at least one gated power domain (210).
