This paper presents a reverse power distribution network (PDN) for integrating low power RF-DC conversion with power distribution unit (PDU) for mW IoT applications. This system is differentiated from most wireless power transfer systems by operating at RF, for decreased coil area. By using a RF source, integration issues from the different capacitance needs of the RF rectifier and PDU emerge. The reverse PDN is applied to a 2 coil system with continuous power demand and 4 coil system with discontinuous power demand. The target impedance and design metrics for the reverse PDN for both systems is discussed. The design of the reverse PDN is presented, through capacitor modeling and selection and modeling of layout effects. Both designs are fabricated with a RF near field integrated board and verified through measurement. Both the 2 coil and 4 coil systems are unable to supply the regulated output without the reverse PDN but successfully supply the desired regulation with the reverse PDN. The reverse PDN is a necessary component to optimally integrate RF near field wireless power transfer with regulated output for low power IoT applications.
