An innovative invert charge recovery logic structure

In this paper, we propose a new energy saving boost logic structure named Invert Boost Logic(IBL). This design belongs to the Boost Logic family and inherits the same two-phase structure. Transistor numbers, layout area and power consumption reduce significantly by virtue of this novel design. Driven by two opposite phased power clocks, it can maximize its gate drivability by increasing the logic power supply voltage thanks to the recycling ability of the AC energy sources as well as two latches. Energy cut could be as high as 60% at GHz-Class frequencies.
