In this paper, we present a novel concept of "energy recycling" within a circuit. Energy which is normally discharged, is "stored" and used in subse- quent clock cycles. This "stored" energy, is used to partially precharge rising (0 + 1) nodes in the circuit. These partially precharged nodes, consume a smaller amount of charge from the power supply. For example, up to 87.5% savings in energy can be obtained on a 16 bit data bus, with 8 storage capaci- tances. The energy savings are approximately 45% more than the technique in [l] which uses energy recovery and no energy storage.
