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.
