    摘要： 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.

    摘要： Embodiments circuits provide a transistor body bias voltage so that the ratio of ION to IOFF is constant over a range of temperature, where ION is a transistor current when ON and IOFF is a (leakage) transistor current when OFF. In one embodiment, a nFET is biased to provide ION to a current mirror that sources a current AION to a node, a nFET is biased to provide IOFF to a current mirror that sinks a current BIOFF from the node, and an amplifier provides feedback from the node to the body terminals of the nFETs so that at steady state AION=BIOFF, where A and B are constants independent over a range of temperature. In this way, the ratio ION/IOFF is maintained at B/A for some range of temperatures. Other embodiments are described and claimed.
