Abstract
Embodiments of the present invention provide systems and methods for controlling circuit power consumption by adjusting the body voltage to the circuit. A preferred embodiment of such a method can be generally described as a method comprising the following steps: detecting a temperature change at the circuit; and adjusting a body voltage to a transistor in the circuit such that the power consumption is controlled. On the other hand, one embodiment of a system for controlling the power consumption of a circuit can be implemented with a device having structure for detecting a temperature change at the circuit and for adjusting a body voltage to the circuit responsive to said temperature change at the circuit.
