ABSTRACT:
An integrated circuit has a power grid and a set of independently switchable voltage islands, together with a system and method for measuring the voltage and history of the voltage on the power grid to determine the correct time to allow a large capacitive load (such as a voltage island) to be switched on to or off the power grid.
