摘要

This paper deals with an active load impedance design to enhance adaptive reconfigurable rectifier performance. The proposed design aim is to address issues raised by early breakdown voltage effect in conventional rectifiers and extends the rectifier operation for wider input power range. The active load, introduced to actively modulate and operate as switch for various terminations at both low and high RF input power levels, achieves 40% of RF-DC power conversion efficiency over a wide dynamic range of input power from -17 dBm to 32 dBm, while exhibiting 80% of peak power efficiency at 12 dBm. The active load power harvester was designed to operate in the 915 MHz ISM band and suitable for Wireless Power Transfer applications.
