N2 - Charge-recycling based AC computing has recently been proposed to significantly increase energy efficiency in wirelessly powered devices. The power consumption is reduced by 1) eliminating the rectification and regulation stages of traditional DC computing and 2) recycling charge through AC computing. An alternative charge-recycling mechanism is proposed in this paper that does not require a phase shifter or peak detector, thereby reducing the overhead power consumption. Simulation results in 45 nm technology demonstrate that an additional 60% reduction in power consumption can be achieved while operating at the same frequency. As compared to the traditional case, power consumption is reduced by more than an order of magnitude.
