Abstract
A functional circuit is coupled to a power supply conductor by at least one power gating transistor. A switching device applies a gate drive voltage to a gate terminal of the power gating transistor via a resistive element. The power gating transistor provides a Miller capacitance between its drain and gate terminals. The Miller capacitance, the resistance of the resistive element, and the drive strength of the switching device are configured such that, in response to the switching device switching the gate drive voltage to allow more current to pass through the power gating transistor, the Miller capacitance provides a feedback mechanism competing against the switching device to reduce the slew rate of the gate drive voltage such that the current passing between the power gate supply conductor and the functional circuit through the power gating transistor is less than the saturation current of the power gating transistor.
