Abstract
A method of energy harvester reconfiguration for a simultaneous wireless information and power transfer (SWIPT) receiver including receiving an input power from an RF signal, determining whether a Nblock-th energy block is activated based on a condition for operating the Nblock-th energy block having a maximum valid input power, among Nblock energy blocks each having a predetermined valid input power, in response to the Nblock-th energy block being determined activated, determining a number of energy harvesting circuits that are activated, among a plurality of energy harvesting circuits included in the Nblock-th energy block, based on power conversion efficiency, and reconfiguring power input in the Nblock-th energy block and the plurality of energy harvesting circuits included in the Nblock-th energy block, based on the determination and result of determination.
