Abstract

The invention provides an integrated circuit and its power management method. The integrated circuit comprises two power supply ends configured to supply power for the integrated circuit, wherein thepower supply end comprises a positive power supply end and a grounded end, and the voltage at the positive power supply end (VDD) and the voltage at the grounded end (VSS) limit the logic level rangetogether; a logic part selecting from one of a logic gate and a storage unit and including a sleep transistor which is in series connection with one of the power supply end; a voltage generator configured to selectively generate the voltage out of the logic level range; a circuit configured supply the voltage out of the logic level range to the sleep transistor in a power-saving mode period; and avoltage regulator configured in the power-saving mode period to control the voltage generator so as to completely reduce the leakage current of the sleep transistor and provided with an emulated sleep transistor. The invention can minimize the static leakage and reduce the complexity of the fabrication technology for the integrated circuit.
