Using　both　the　modified　supply　voltage　and　body　voltage,　an　optimized　keeper　technique　is　presented　in　this　paper　to　tradeoff　the　performance　of　domino　OR　gates.　The　simulation　results　show　that　the　novel　technique　can　highly　improve　power/speed　efficiency　and　robustness　to　noise.　In　addition,　because　of　employment　of　body　biased　voltage,　the　optimized　keeper　technique　enables　to　minimize　effect　of　the　strong　process　parameter　variation.
