PROJECT TITLE :

RF Power Gating: A Low-Power Technique for Adaptive Radios - 2016

ABSTRACT:

In this paper, we have a tendency to propose a low-power technique, known as RF power gating, that consists in varying the active time ratio (ATR) of the RF front finish at a symbol time scale. This method is particularly compatible to adapt the power consumption of the receiver to the performance needs without changing its architecture. The result of this system on the bit error rate (BER) performances is studied for a basic estimator in the precise case of minimum-shift keying signaling. A system-level energy model is additionally derived and discussed to estimate precisely the ability reduction based mostly on the characteristics and the power consumption of every block. This model permits highlighting the different contributors of the facility reduction. The BER results and the energy model are finally merged to see the most effective ATR meeting the design constraints. Applying this method to the IEEE 802.fifteen.four standard, this paper shows that an ATR of twentyp.c is a good tradeoff to fulfill the packet error rate constraint whereas maximizing the energy reduction ratio. Using typical block power consumptions, an energy reduction ratio around twentyp.c can be reached. Even higher energy reduction ratios (~sixtypercent) are also achievable when most of the blocks are power-gated.
