Abstract: A leakage manager system for adequately minimizing static leakage of an integrated circuit is disclosed. The leakage manager system includes a generator configured to generate a control signal to be applied to a sleep transistor. A monitor is configured to determine whether to adjust the control signal to adequately minimize the static leakage. In some embodiments, the monitor includes an emulated sleep transistor. A regulator is configured to adjust the control signal depending on the determination.

Abstract: Example systems and methods for a charge pump are disclosed. A charge pump may comprise a pump capacitor configured to charge when electrically coupled to a sleep signal and discharge when electrically coupled to an output, a means for receiving an alternating signal which electrically couples a VDD signal or an output to the pump capacitor based on a state of the alternating signal, a means for receiving a complement of the alternating signal which electrically couples the sleep signal with the pump capacitor based on a state of the complement of the alternating signal, and a means to electrically couple the alternating signal and the complement of the alternating signal to a node based on the state of the alternating signal and the state of the complement of the alternating signal.

Abstract: To minimize static leakage of an integrated circuit, a charge pump generates a negative voltage to be applied to a “sleep” transistor cascaded to a logic gate of the integrated circuit. An adaptive leakage controller determines continuously or periodically whether to adjust the negative voltage to minimize the static leakage. A negative voltage regulator adjusts the negative voltage depending on the determination. Some embodiments determine whether to adjust the negative voltage by monitoring one or more parameters of the sleep transistor. Some embodiments determine whether to adjust the negative voltage by monitoring one or more parameters of an emulated sleep transistor.
