An integrated circuit includes a plurality of power gating elements for controlling power applied to a first module which is in a powered off state, while a second module is in a powered on state, the second module being coupled to receive at least one signal from the first module when the first module is powered on. A a synchronization controller is provided for controlling the power gating elements to ramp up the power gated to the first module in order to power it up and, for a time while the power gated to the first module is below a first level, reducing the power gated to the second module, and for a time when the power gated to the first module is above the first level, increasing the power gated to the second module.
