A Multi-Rectenna, Single-Output, Power Combine-and-Regulate Boost Converter for 5.8GHz Wireless Power Receiver Achieving 3.1W Over 50m-Distance
This paper presents a multi-input single-output power combine-and-regulate (MISO-PCR) converter chip for a 5.8GHz WPT receiver (Rx). The MISO-PCR simultaneously collects, combines, and converts the multiple power from 30 GaAs rectennas into a single regulated output (28V). Fabricated in a 180nm BCD, the chip enables the Rx system—paired with a beamforming Tx—to deliver a 3.1 W power at a 50m distance.
