Estimating the term…
According to one embodiment, a system is provided that includes at least one power gated component and two or more power switch transistors configured to provide one or more conductive paths between a common power supply rail, the at least one power gated component, and a ground. The two or more power switch transistors each include a source terminal, a drain terminal, and a gate terminal configured to control current flow between the source and drain terminals. The system also includes a rotating voltage control coupled to the gate terminals and configured to apply a sequence of control signals rotating between an on-state and an off-state to each of the gate terminals while the at least one power gated component is turned on. A switch activation ratio level is programmable to set a number of power switch transistors in the on-state relative to a total number of power switch transistors.
A system, comprising:
A method for rotating voltage control in a system comprising at least one power gated component and two or more power switch transistors configured to provide one or more conductive paths between a common power supply rail, the at least one power gated component, and a ground, the two or more power switch transistors each comprising a source terminal, a drain terminal, and a gate terminal configured to control current flow between the source and drain terminals, the method comprising:
