ABSTRACT:
According to the preferred embodiment, a device and method for reducing power consumption by reducing unneeded node toggling is provided. The preferred embodiment reduces unneeded node toggling in a circuit by utilizing either a pull-up or pull-down transistor to pull the input of the circuit to a state that minimizes power consumption during periods in which the circuit is inactive. By tying the circuit input high or low during inactivity, node toggling is reduced or eliminated in that circuit. In the preferred embodiment, the inputs to the circuit all pulled after a time of inactivity which is proportional to the leakage current of the leakiest transistor in the circuit. By timing the input pulling proportional to the leakage current, the power consumption is minimized without excessive power loss caused by the pulling itself.
