In this study, a phase error correction algorithm is proposed for radio frequency (RF) energy harvesting through a fully differential RF-to-DC converter with two antennas. The system keeps one of the inputs as the reference and adjusts the phase of the other input. A 2-bit resolution is used to demonstrate how the concept works. The system aims to operate without an external battery. System-level simulation results prove that through the proposed concept, the efficiency of the harvester can be considerably boosted for an RF harvester with two antennas.
