ABSTRACT:
A circuit and method are provided for reducing the DC power consumption of clocked ratioed digital logic circuits. The circuit includes switching circuitry designed to analyze the voltage transitions of a ratioed digital logic circuit and based on such transitions, control the DC current flow through the entire circuit. Through the regulation of DC current flow through a digital logic circuit, the present invention reduces the detrimental effects of hot-electron effects and electromigration concerns which cause digital circuitry to fail. The circuit and method are illustrated by way of a ratioed logic NOR function employing MOSFET technology.
