    • A system and method to reduce leakage power while minimizing performance penalties and noise is disclosed. In accordance with one embodiment of the invention, the system includes at least one sleep transistor operatively coupleable between a system power supply and at least one circuit powered by the system power supply to control the application of power to the circuit. The sleep transistor is also operatively coupleable to receive a sleep control signal to turn the sleep transistor on and off. A body bias voltage generator is operatively coupleable to a body of the at least one sleep transistor to substantially reduce leakage current when the sleep transistor is non-operational or idle and to improve the operational characteristics of the sleep transistor when the transistor is operational by reducing the performance penalty of the sleep transistor and by reducing impact of noise on the circuit and other devices.
    • 公开了一种降低泄漏功率同时最小化性能损失和噪声的系统和方法。 根据本发明的一个实施例,该系统包括至少一个休眠晶体管,其可操作地耦合在系统电源和由系统电源供电的至少一个电路之间,以控制对电路的功率的施加。 休眠晶体管也可操作地耦合以接收睡眠控制信号以打开和关闭睡眠晶体管。 身体偏置电压发生器可操作地耦合到至少一个睡眠晶体管的主体,以在休眠晶体管不可操作或空闲时基本上减少泄漏电流,并且当晶体管通过降低工作时改善睡眠晶体管的操作特性 休眠晶体管的性能损失,并减少噪声对电路和其他器件的影响。
